How long is U.S. Route 101?
U.S. Route 101
The nearly highway's northern terminus is in Tumwater, Washington: the route remains along the Olympic Peninsula's coastal perimeter west, north, and east; the northernmost point on the highway is in Port Angeles. The southern terminus of US 101 is in Los Angeles at the East Los Angeles Interchange, the world's busiest freeway interchange.
U.S. Route 101 in Oregon
The next stretch of US 101 (between Florence and Newport) closely follows the coastline, providing a wide view of the ocean. Towns between these two cities include Yachats, Waldport, and Seal Rock. Eventually, the highway crosses the Yaquina Bay Bridge into Newport. Just before the bridge lies the Oregon Coast Aquarium; on the other side of the bridge is the famed Newport waterfront.
Massachusetts Route 101
Route 101 is a north–south state highway in Massachusetts.
New Hampshire Route 101
The western terminus of NH 101 is in Keene at the junction with New Hampshire Routes 9, 10 and 12. The eastern terminus is in Hampton Beach at the junction with Ocean Boulevard (NH 1A). The total length of NH 101 is . However, the New Hampshire Department of Transportation has installed mileposts on the freeway section east of Interstate 93 that begin at mile 100.
New Jersey Route 101
Route 101 was a proposed state highway in the U.S. state of New Jersey. It was planned in 1939 as a freeway from Kearny to Hackensack, but it was never built. Route S101 was a northern extension of Route 101 planned at the same time from Hackensack through Paramus to the New York state line at Montvale. The section from Hackensack to Paramus was never built; the section from Paramus to the state line was built as part of the Garden State Parkway (Route 444) instead. Both designations were repealed in the 1953 renumbering.
U.S. Route 101
US 101 enters Oregon south of Brookings, and is seldom out of sight of the Pacific Ocean except the northern end near Astoria and from Port Orford to Florence other than a viewpoint south of Winchester Bay; with another major exception being a significant inland stretch south of Tillamook, Oregon. It crosses the Chetco River at Brookings, the Rogue River in Gold Beach, the Coquille River just north of Bandon, Coos Bay at North Bend via the McCullough Bridge, named after the engineer who designed a series of bridges built on the Oregon Coast in the 1930s, the Umpqua at Reedsport, the Siuslaw in Florence, Yaquina Bay at Newport, and Youngs Bay and the Columbia River at Astoria. The stretch between Florence and Yachats is considered one of the more attractive segments of this highway. There are at least 86 Oregon state parks along the Pacific coast, including the Heceta Head Lighthouse. There are also many scenic bridges along the Oregon Coast that carry US 101, such as the Yaquina Bay Bridge in Newport. Because US 101 forms the main street of almost all of the coastal towns in Oregon (with the exception of Cannon Beach, Pacific City and a few others), traffic is often congested and slow in the summer months. The highway crosses the mouth of the Columbia River over the Astoria-Megler Bridge at Astoria into Washington, and follows the Columbia downstream to Ilwaco.
Oregon Route 42 (OR 42 and OR 42S have taken over old portions of US 101 around Coquille following a bypass. Reconstructions of US 101 in the post-World War II era shortened distances and eliminated the worst narrow curvy sections in various places on the Oregon Coast.
U.S. Route 101 in California
US 101 crosses the Pajaro River into Santa Clara County as a four-lane highway, with an interchange at SR 25 a few miles later. Upon reaching Gilroy, it becomes the South Valley Freeway (as in South Santa Clara Valley), and at the same time, it expands to three lanes in each direction. It then enters Silicon Valley when reaching Morgan Hill, and shortly afterwards expands to four lanes in each direction, with an HOV lane in the middle, before reaching San Jose. From San Jose to San Francisco, US 101 is known as the Bayshore Freeway as it passes through Palo Alto and the other major communities along the San Francisco Peninsula.
US 101 is called the James Lick Freeway, named for James Lick, a philanthropist, from the San Francisco county/city line, through the interchange with I-280 at the Alemany Maze, until the junction with the San Francisco Skyway (I-80) and the Central Freeway near the city's Civic Center. US 101 continues in a northwestern direction on the Central Freeway, and then leaves the freeway, on Mission Street (northbound) and South Van Ness Avenue (southbound), to run north on Van Ness Avenue. At the intersection of Van Ness Avenue and Lombard Street, US 101 heads west on Lombard Street, and then on Richardson Avenue, entering The Presidio, where it becomes a divided highway again (the Presidio Parkway). It is then joined by Route 1 before approaching and crossing the Golden Gate Bridge.
California Coast Ranges
U.S. Route 101 runs generally north-south in the valleys between the Outer and Inner Northern Coast Ranges.
Texas State Highway 101
SH 101 begins at an intersection with U.S. Route 81 on the far southeast side of Bowie, and travels southeast about 7 miles to Sunset. This section was the original routing of US 81 and US 287 before an upgraded routing was built for those routes. This section of SH 101 also remains within a mile of the upgraded US 81/US 287 along the entire route. In Sunset, the route sutns to the south, departing from it parallel routing with the US Routes, and continues southward through Chico to its southern terminus on the north side of Bridgeport, where it meets U.S. Route 380 and SH 114. This section from Sunset to Bridgeport was a previous routing of SH 114 before it was redirected westward in 1976.
Missouri Route 101
Route 101 is a short highway in southern Missouri. The route starts at Arkansas Highway 101 at the Arkansas–Missouri state line, and travels northeastward. It travels through the city of Bakersfield, intersecting Route 142. The road then continues north to its northern terminus at U.S. Route 160 (US 160) in Caulfield. The route was designated in 1941, after a supplementary route was renumbered.
Missouri Route 101
Route 101 starts at the Missouri–Arkansas state line, at the northern terminus of Arkansas Route 101 and County Road 583 (CRD 583). The road travels through a forest and parallel to the state line for the first . At CRD 588, the route turns northeastward, intersecting a few driveways until it reaches CRD 586, where it turns northward past the intersection. Route 101 travels eastward before it intersects CRD 584, and enters the corporate limits of Bakersfield at CRD 585. The route briefly travels north and intersects Route O, which leads to the unincorporated area of Udall. The road enters the center of the city at Main Street and curves northward at the western terminus of Route 142. Route 101 leaves the city north of Starks. The road enters through a mix of farmland and forests as it continued through southeast Ozark County. At CRD 101-174, the route begins to turn northeastward and later intersects CRD 597. Route 101 crosses the county line at CRD 7890, and enters Howell County. Once inside the county, the route turns north at Route YY and intersects CRD 7690. The road turns to the northeast in the community of Caulfield, and ends at US 61 in a T-intersection.
New Hampshire Route 101
New Hampshire Route 101A (abbreviated NH 101A) is a east–west highway in Hillsborough County, New Hampshire, connecting Milford and Nashua. It also runs through Merrimack and Amherst, and very briefly touches Hollis.
U.S. Route 301
U.S. Route 301 (US 301) is a spur of U.S. Route 1 running through the South Atlantic States. It currently runs 1,099 miles (1,769 km) from Biddles Corner, Delaware at Delaware Route 1 to Sarasota, Florida at U.S. Route 41. It passes through the states of Delaware, Maryland, Virginia, North Carolina, South Carolina, Georgia, and Florida. It goes through the cities of Annapolis, Maryland; Richmond and Petersburg, Virginia; Rocky Mount, Wilson, and Fayetteville, North Carolina; Florence, South Carolina; Statesboro and Jesup, Georgia; and Ocala, Zephyrhills, Brandon, and Sarasota, Florida.
U.S. Route 101 in Oregon
North of Tillamook, the highway passes on the eastern shore of Tillamook Bay, through towns such as Bay City and Garibaldi, before reuniting with the ocean. It then continues north along the Pacific through towns such as Rockaway Beach and Nedonna Beach; the next major towns are Nehalem and Manzanita, both on Nehalem Bay. The highway then continues north along the coastline through rugged terrain until it reaches the city of Cannon Beach. Unlike most coastal cities in Oregon, a bypass (in two-lane freeway configuration) was built around Cannon Beach; US 101 follows the bypass alignment. A few miles north of Cannon Beach is an interchange with U.S. Route 26, followed by the city of Seaside. (Until recently, U.S. 26 continued north towards Astoria, sharing an alignment with US 101; however ODOT truncated U.S. 26 to its current terminus at the interchange with 101 several years ago.)
U.S. Route 601
U.S. Route 601 (US 601) is a north–south United States highway that runs for from U.S. Route 321, near Tarboro, South Carolina, to U.S. Route 52, in Mount Airy, North Carolina.
Oklahoma State Highway 101
State Highway 101 begins at US-59 approximately north of Sallisaw. From this terminus, SH-101 travels due east, crossing over Little Sallisaw Creek shortly before passing through the unincorporated place of Akins. Two miles (3.2 km) east of Akins, the road makes a sharp turn northward. During this -long stretch of north–south roadway, the road passes Sequoyah's Cabin. The road gradually curves back to the east as it crosses Big Skin Bayou. Upon encountering Black Creek, a tributary of the bayou, the road makes an abrupt turn back to the north.
U.S. Route 301 in Maryland
US 301 is a Blue Star Memorial Highway for its entire length in Maryland. The Federated Garden Clubs of Maryland declared the U.S. Highway a Blue Star Memorial Highway as a tribute to the United States Armed Forces in 1948, and a 1953 resolution signed by Governor William Preston Lane, Jr., officially dedicated US 301 as such. The highway's primary name from the Potomac River to Bowie is Robert Crain Highway. Robert Crain was a Charles County farmer and lawyer who spearheaded the construction of a new highway to directly connect Baltimore and Southern Maryland that was completed in 1927. Along its concurrency with US 50 and unsigned I-595 from Bowie to the Severn River, US 301 follows John Hanson Highway. The freeway is named for John Hanson, the first President of the Continental Congress in 1781.
Utah State Route 71
The state legislature created State Route 71 in 1931, running south from US-40 (2100 South) along 900 East and through Draper, Corner Canyon, and Alpine to US-50/US-89/US-91 (now solely US-89) in American Fork. However, the portion across the Traverse Mountains between SR-111 (12300 South) in Draper and Alpine was never built, and was removed from the state highway system in 1935; at the same time, the southern piece from Alpine to American Fork was renumbered SR-74. In 1957, most of SR-71 was moved west two blocks to 700 East, the south end was truncated to 7700 South north of Sandy (replaced by an extension of SR-111), and the north end was extended to SR-181 (South Temple Street). This change was partially reverted in 1959, when the south end was extended back to Draper over what had just become SR-111. In 1969, the north end was cut back four blocks to SR-186 (400 South), and the south end was extended west along what had been SR-111 (created in 1931) to SR-68 (Redwood Road) in Riverton. A short extension west from the south end to the new SR-154 (Bangerter Highway) was made in 2001, pending reconstruction by the state.
Kentucky Route 101
Kentucky Route 101 (KY 101) is a north–south highway traversing three counties in south central Kentucky.
U.S. Route 101 in California
US 101 crosses into the Mendocino County line as a freeway for one mile (1.6 km), but then narrows to an expressway through the Russian River canyon and eventually a two-lane road south of Hopland, the first time since leaving San Francisco. Just before reaching Ukiah, US 101 becomes a four-lane freeway. In the community of Calpella, SR 20 merges with US 101 for the next to Willits. The freeway portion ends as the combined US 101 and SR 20 ascend the Ridgewood Summit, the highest elevation along the route's trek through California. As 101 resumes freeway status just south of Willits, SR 20 splits from 101 shortly before 101 suddenly reverts to a 2-lane undivided freeway and eventually a highway north of Willits.
Maine State Route 101
SR 101 begins in the south at an intersection with US 1 in Kittery, just northeast of its intersection with SR 236, where US 1 Bypass meets its northern end. Near this intersection is the exits 2 and 3 interchanges from the Maine Turnpike. The route heads northwest, intersecting local roads as it passes east of the town of Eliot. SR 101 intersects with SR 236 and enters the southern tip of South Berwick. The highway continues a short distance northwest before crossing the Piscataqua River into Dover, New Hampshire. Upon crossing into New Hampshire, SR 101 ends and the road continues as unnumbered Gulf Road. Motorists following this road west will soon come across signage leading to New Hampshire Route 4 towards downtown Dover. No advance signage exists in the reverse direction, with Gulf Road simply transitioning to SR 101 upon crossing into Maine.
U.S. Route 101 in California
Although the highway has been superseded in overall importance for transportation through the state by Interstate 5 (I-5), US 101 continues to be the major coastal north–south route that links the Greater Los Angeles Area, the Central Coast, the San Francisco Bay Area, and the North Coast (Redwood Empire). Generally referred to as "101" by residents of Northern California, in Southern California it is often called "The 101" (pronounced "the one oh one"). The highway has portions designated as the Santa Ana Freeway, the Hollywood Freeway, the Ventura Freeway, South Valley Freeway, and Bayshore Freeway. The Redwood Highway, the northernmost segment of the highway, begins at the Golden Gate and passes through the world's tallest and only extensive preserves of virgin, old-growth coast redwood trees.
New Mexico State Road 101
NM 101 first appears on 1940 roadmap, as a connector between State College (future NMSU) and US 80/US 85 south of Las Cruces. The road construction was probably related to the New Mexico State College introducing Air Mechanics Courses starting at some point prior to 1941. The Air Mechanics Building & the Hangar Lake Building both were erected in 1941 (according to plaques on the buildings), and State College Airport was constructed around the same time. In 1960s the road was extended further east to I-25. In 1988, the New Mexico Department of Transportation (NMDOT) went through a radical road renumbering program, and NM 101 was extended further west to NM 28. In 2001 a portion of this highway between South Main Street and Telshor Boulevard was transferred to the city of Las Cruces shortening NM 101 to its current length.
Wisconsin Highway 101
State Trunk Highway 101 (often called Highway 101, STH 101 or WIS 101) is a state highway in the U.S. state of Wisconsin. It runs south–north in northeast Wisconsin from US 8 in Armstrong Creek to WIS 70, US 2 and US 141 in Florence. WIS 101 meets WIS 70 near Keyes Lake, and the two highways run concurrently for until their shared terminus. The highway also serves the community of Fence and the areas surrounding the Pine and Popple rivers. WIS 101 is maintained by the Wisconsin Department of Transportation.
Minnesota State Highway 101
The U.S. Highway 169 bypass east of downtown Elk River was built in 1961, and old Highway 101 was extended north on old Highway 169 ("Jackson Avenue") to the north end of the bypass. Later, in 1968, the bypass was extended south to old State Highway 152 in Rogers, and Highway 101 was realigned to be concurrent with old Highway 152 and use the new bypass from Rogers north to Elk River. The original alignment of Highway 101 was turned over to the counties (renumbered as County 13 / "Brockton Avenue" in northern Hennepin County and County 42 in Wright County), and the extension north of downtown Elk River was renumbered "State Highway 201" until 1987. Highway 101 was realigned to the present day "County Road 101" between Savage and downtown Shakopee in 1940. In 1964, the State Highway 5 bypass of downtown Chanhassen was built, but Highway 101 remained on the old route until the 1980s, when it was moved to the bypass. The relocation of State Highway 55 at Plymouth / Medina, and with it the brief Highway 55 / 101 concurrency, came in 1942 west of and 1954 east of the intersection with the old alignment.
U.S. Route 101
In Southern California, the highway is a heavily traveled commuter route serving the Northwest portion of the Greater Los Angeles area; this includes Ventura County communities in the West Conejo Valley and in the Oxnard Plain, along with Los Angeles County communities in the East Conejo Valley and San Fernando Valley. The route is the Santa Ana Freeway from East Los Angeles to Downtown Los Angeles. It becomes the Hollywood Freeway north of Downtown Los Angeles through the Cahuenga Pass, before turning west and becoming the Ventura Freeway. Communities along the alignment include Hollywood and the southern edge of the San Fernando Valley, and the cities of Hidden Hills, Calabasas, Agoura Hills, Westlake Village, Thousand Oaks (includes Newbury Park), Camarillo, Oxnard, Ventura, Santa Barbara, Santa Maria, San Luis Obispo and Atascadero.
In Northern California, US 101 is the primary coastal route providing motorists access in and out of the San Francisco Bay Area, as well as the primary commuter route between San Francisco and the North Bay. It is one of two major freeway routes connecting the South Bay and Silicon Valley with San Francisco and the North Bay. It serves as a more urban alternative to the rural I-280, as US 101 runs through Peninsula cities closer to the Bay, while I-280 runs closer to the Santa Cruz Mountains and Skyline Boulevard. Through northern San Francisco, US 101 remains routed on congested city streets due to freeway revolts, leaving the city on the iconic Golden Gate Bridge. It then departs the immediate coast and continues through wine country and Redwood forests until it re-emerges coast-side at Eureka. The route provides access through the extraordinarily rugged and scenic terrain of the North Coast and into vast groves of protected Redwoods in area parks, including Redwood National and State Parks before reaching the Oregon border.
U.S. Route 101 in California
In the San Francisco Bay Area, US 101 was originally divided. US 101W followed the same general right-of-way of today's US 101 through the region, primarily along what was originally signed as Bayshore Boulevard. US 101E then generally followed the right-of-way taken by today's I-880 from San Jose to Oakland, then across the Carquinez Bridge to follow what is now SR 37, joining US 101W. The US 101E designation was removed by the 1940s and became SR 17 (later designated as I-880 and the westernmost section I-580), running from San Jose to Oakland and then across the Richmond–San Rafael Bridge. Meanwhile, Bayshore Boulevard was later redesignated as the US 101A bypass and then eventually upgraded to what is now the Bayshore Freeway. The first stretch that was completed between Redwood City and South San Francisco was the Bay Area's first freeway when it opened in 1947. After the entire Bayshore Freeway was completed in the early 1960s, the old alignment along the peninsula was renumbered and renamed as SR 82/El Camino Real.
Oregon Route 131
Oregon Route 131 (OR 131), known as the Netarts Highway No. 131 (see Oregon highways and routes), is a state highway in the U.S. state of Oregon. The route runs from the coastal community of Oceanside to an intersection with U.S. Route 101 (US 101) and OR 6 in Tillamook, Oregon. The highway is long. Netarts Highway No. 131 was established in 1940, and was designated OR 131 in 2002.
Arizona State Route 101
Loop 101 has interchanges with almost all area freeways, including: Loop 202, US 60, SR 51, Interstate 17, and Interstate 10 along its 61-mile (98 km) route.
U.S. Route 101
The US 101E designation was removed by the 1940s and became SR 17 (later I-880 and I-580) between San Jose and Santa Cruz. As the Bayshore Freeway was built along the east side of the San Francisco peninsula in the early 1950s, old US 101 along the El Camino Real was posted as US 101 Alternate or US 101A, and the freeway was marked US 101 Bypass or US 101B. In 1964, when California renumbered numerous state highways, El Camino was renumbered SR 82 and the Bayshore Freeway lost the bypass designation.
U.S. Route 101
The Washington section of US 101 is defined in the Revised Code of Washington §47.17.165.
U.S. Route 101 in California
By the early 1950s, traffic had become very heavy on US 101 through Oceanside and Carlsbad. The US 101 freeway bypass (Oceanside-Carlsbad freeway bypass) was built in 1953 and completed in 1955 by the California Department of Public Works (now Caltrans) and brought up by the San Diego Highway Development Association on a US 80/US 101 discussion on how to resolve the huge traffic loads on US 101 in Oceanside. Today it is part of I-5 and Palomar Airport Road. It follows I-5 from Coast Highway (former Hill Street exit) in Oceanside to Palomar Airport Road in Carlsbad. From there the US 101 bypass went onto Palomar Airport Road to merge with US 101 Bus. on Carlsbad Boulevard. As it approached the Coast Highway/SR 76 exit on southbound I-5 in Oceanside, US 101 Bus. split off. US 101 Bus. followed the original US 101 through downtown Oceanside and Carlsbad as former Hill Street/Carlsbad Boulevard (CR S-21) while the US 101 freeway followed modern I-5 and Palomar Airport Road. The south end of the freeway bypass is Carlsbad Boulevard and Palomar Airport Road and the north end is I-5 and the Coast Highway/SR 76 exit. The south end was modified after US 101 was decommissioned between the East Los Angeles Interchange in Los Angeles and the Mexican border in San Ysidro. This freeway construction by the California Department of Public Works put US 101 on an all new highway route alignment to relieve Oceanside and Carlsbad of their very heavy bumper-to-bumper burdensome traffic problem. Also before the bypass in the 1950s, US 101 followed North Coast Highway (formerly Hill Street) from San Luis Rey Mission Expressway (SR 76 and north end of the Oceanside–Carlsbad freeway bypass) to Harbor Drive. From there it followed Harbor Drive to Vandergrift Boulevard, San Rafael Drive, and the freeway onramp for I-5 north near the Camp Pendleton north entrance guardhouse gate. It merges with the I-5 northbound onramp to shoot onto the southbound lanes of I-5 to follow the freeway lanes all the way to Las Pulgas Road in Camp Pendleton.
Kentucky Route 101
KY 101 follows Main Street through the city, in the center of which the highway intersects CSX's Main Line Subdivision rail line. KY 101 continues through the Smiths Grove Historic District. The highway passes a block to the east of the J.L. Wright House and a block to the west of Smiths Grove Presbyterian Church. KY 101 passes the Smiths Grove Baptist Church one block south of where the route turns west onto 6th Street for two blocks. At the west city limit of Smiths Grove, the highway turns north and leaves the city along Smiths Grove-Scottsville Road. KY 101 passes through a pair of more-than-right-angle curves to the west and then north before reaching US 31W (Louisville Road), which the state-numbered highway joins heading west.
Sonoma County, California
U.S. Route 101 is the westernmost Federal highway in the U.S.A. Running north/south through the states of California, Oregon, and Washington, it generally parallels the coastline from the Mexico–US border to the Canada–US border. Highway 101 links seven of the county's nine incorporated cities: Cloverdale, Healdsburg, Windsor, Santa Rosa, Rohnert Park, Cotati, and Petaluma. It is a freeway for almost its entire length within the county, except for a section south of Petaluma.
U.S. Route 101
U.S. Route 101, or U.S. Highway 101 (US 101) is a north–south United States Numbered Highway that runs through the states of California, Oregon, and Washington, on the West Coast of the United States. It is also known as (The Royal Road) where its route along the southern and central California coast approximates the old trail which linked the Spanish missions, pueblos, and presidios. It merges at some points with California State Route 1 (SR 1).
U.S. Route 101 in California
From Paso Robles to Salinas, US 101 is an expressway known as the Salinas River Valley Highway, since the Salinas River Valley extends from Santa Margarita to the SR 156 junction in Prunedale. US 101 resumes freeway status between San Miguel and King City, passing through the smaller towns of Camp Roberts, Bradley, and San Ardo, as well as the San Ardo Oil Field about south of San Ardo. Near this point, the wide agricultural bottomlands of the Salinas Valley begins. North of King City, US 101 once again switches intermittently between freeway and expressway status, passing through Greenfield, Soledad, Gonzales, and Chualar before reaching Salinas. Shortly after leaving Salinas, US 101 joins SR 156 in Prunedale for about . After crossing the San Benito County line, SR 156 splits from US 101 near San Juan Bautista while US 101 continues northward mostly as a four-lane highway until it reaches Gilroy.
U.S. Route 101
Before the Golden Gate Bridge was completed, US 101 was divided in the San Francisco Bay Area. US 101W followed the same general right-of-way of today's US 101 from San Jose to San Francisco. US 101E generally followed the right-of-way taken by today's I-880 from San Jose to Oakland, then across the Carquinez Bridge to follow what is now SR 37, joining US 101W. Since there was no Golden Gate Bridge yet, US 101W used a ferry across the Golden Gate Strait. As today, US 101W proceeded up Van Ness, but without any left turn at Lombard, ending at the Hyde Street Pier. From there, motorists would drive onto a ferry boat which would cross the Golden Gate to Sausalito, where they would drive off the ferry directly onto the main street of Sausalito, which was signed for US 101 once again.
Rhode Island Route 101
Route 101 begins at the Connecticut state line between the towns of Killingly and Foster as a continuation of Connecticut Route 101. The route, known locally as Hartford Pike, runs for about through several reservoirs before ending at US 6 Bypass in the town of Scituate, near the north edge of the Scituate Reservoir. Route 101 passes near Jerimoth Hill, the highest point in Rhode Island.
Arkansas Highway 101
Highway 101 (AR 101, Ark. 101, and Hwy. 101) is a designation for two north–south state highways in north central Arkansas. A western route of runs north from US Route 62/US Route 412 (US 62/US 412) to Missouri Route 101 at the Missouri state line. A second route of begins at Hand Valley and runs north to US 62/US 412.
Indiana State Road 101
The third portion of SR 101 is long and starts at US 52 and SR 1 in Brookville. SR 101 runs concurrent with SR 1 north and then SR 101 heads northeast, leaving SR 1. The highway curves around Brookville Lake and continues due north towards Liberty. The road crosses into Union County and turns northeast again, ending at an intersection with US 27 and SR 44 in Liberty.
California County Routes in zone S
The route was established in 1961.
County Route S20 (CR S20) is a former county highway in the US state of California. As the only county route in Santa Barbara County, it was merged with State Route 1 in 1988 making the southbound SR 1 freeway to go along with Country Route S20 to Vandenberg AFB.
County Route S21 is a south–north running road serving the coastal communities of northern San Diego County, running from San Diego in the south to Oceanside in the north. The route is signed in many places as "Historic Route 101" with the official Historic U.S. 101 shields. S21 follows the prior alignment of U.S. Route 101 through this region. The route is also called "Coast Highway" in some places as well. This route was originally designated in 1968 and is long.
County Route S21 begins at Interstate 5 in the north of San Diego as Genesee Avenue. After proceeding west-northwest for 3/4 mile (1.2 km) it intersects Torrey Pines Road and continues north with that name. The road then travels north into Del Mar, where it is renamed "Camino Del Mar". While in Del Mar the route passes both the historic Del Mar Racetrack and through the historic downtown of Del Mar. In Solana Beach the route moves closer to the coast. Along this stretch it is named "Highway 101" and the city has signed the route along its length with faux U.S. Highway shields that resemble the official U.S. 101 shields in use today along with the state issued Historic 101 shield. While to the north in Encinitas the route's name becomes "Coast Highway 101" also in homage to the old U.S. Route. In Carlsbad it becomes "Carlsbad Blvd". The route is named "Coast Highway" in Oceanside, and comes to an end at Interstate 5 in Camp Pendleton.
U.S. Route 101 in California
U.S. Route 101 (US 101) in the state of California is one of the last remaining and longest U.S. Routes still active in the state, and the longest highway of any kind in California. US 101 was also one of the original national routes established in 1926. Significant portions of US 101 between the Los Angeles area and the San Francisco Bay Area follow El Camino Real, the historic road connecting the former Alta California's 21 missions.
California State Route 41
Except between US 101 in Atascadero and SR 46 near Shandon, SR 41 is part of the California Freeway and Expressway System, and north of SR 46 is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration. Three segmentsfrom SR 1 to US 101, SR 46 to SR 33, and SR 49 at Oakhurst to Yosemite (the Wawona Road)are eligible for inclusion in the State Scenic Highway System, but SR 41 is not officially designated as a scenic highway by the California Department of Transportation. SR 41 is known as the E.G. Lewis Highway from SR 1 to US 101 in San Luis Obispo County, the Dwight David Eisenhower Memorial Freeway from Ventura Avenue in Fresno to Herndon Avenue in Fresno, the Donald DeMers Highway from Jensen Avenue in Fresno to Elkhorn Avenue, the Yosemite Freeway from Elkhorn Avenue to the Fresno-Madera County line, the Southern Yosemite Highway from the Fresno-Madera County line to Yosemite National Park, and the Wawona Road from Fresno to Yosemite National Park.
U.S. Route 101 in Washington
US 101 enters Washington from Oregon on the Astoria–Megler Bridge, a bridge that carries vehicles across the Columbia River near its mouth; it is the longest continuous truss bridge in North America and among the longest of its kind in the world. At the north end of the bridge is an intersection with State Route 401 (SR 401), where US 101 turns west to follow the north bank of the river, forming part of the Lewis and Clark Trail Scenic Byway. The highway passes under Fort Columbia State Park in a tunnel and continues along the Willapa Hills through Chinook towards Baker Bay. At the head of the bay, near Port of Ilwaco Airport, US 101 intersects a short alternate route that bypasses the coastal section of the highway. US 101 then dives southwesterly along the Wallacut River into Ilwaco, where it runs through town as Spruce Street before turning north onto 1st Avenue after an intersection with SR 100.
Willits, California
U.S. Route 101 is the major highway through the Little Lake Valley, passing just east of the Willits city limits, connecting Eureka to the north and San Francisco to the south. State Route 20 forks off of US 101 at a point just south of Willits, follows South Main Street and then heads west, running parallel to and several miles south of the Skunk Train's route, to Fort Bragg. To reduce traffic congestion in the city, especially on all of Main Street, the Willits Bypass project opened to traffic on November 3, 2016, despite the controversy related to its route through protected wetlands.
U.S. Route 101 in California
The US 101 Highway is part of the auto tour route of the Juan Bautista de Anza National Historic Trail, a National Park Service unit in the United States National Historic Trail and National Millennium Trail programs. In 2005, Caltrans began posting signs on roads that overlap with the historic 1776 Juan Bautista de Anza trail route, so that California drivers can now follow the trail.
Texas State Highway 101
State Highway 101 or SH 101 is a state highway in the U.S. state of Texas that runs from Bowie to Bridgeport. It was designated along its route in 1976, running from Bowie southeast parallel to US 81/US 287 along a previous routing of those US Routes, then turning south toward Bridgeport along a previous portion of SH 114.
U.S. Route 101 in California
In the wake of the dot-com bubble expansion, the segment of US 101 between Morgan Hill and San Jose, also known as the Sig Sanchez Freeway, expanded to eight lanes between Cochrane Road and SR 85 exits between 2001 and 2003 and a new interchanged at Bailey Avenue, which had been stuck in development since the 1970s, opened in 2004. Originally, the ten-mile segment was only four lanes (it was planned to have six lanes when opened in 1984). The improved segment was to alleviate the consistent congestion that had expanded as far south as Masten Avenue coming from Gilroy, and as far north as Bernal Road coming from San Jose. Traffic now typically only runs slow between the Bailey Avenue and Dunne Avenue exits.
Crescent City, California
Highway access is provided by U.S. Route 101, which runs directly through the city, connecting the Oregon Coast to the north and Eureka to the south. U.S. Route 199 begins just north of Crescent City and heads northeast to Grants Pass, Oregon. The junction of U.S. Routes 101 and 199 is one of only two junctions of two U.S. Routes in California, the other being the junction of U.S. Routes 6 and 395 in Bishop.
Connecticut Route 101
Route 101 from the western terminus to milepost 6.78 in East Killingly is also known as the Leif Ericson Highway.
New Mexico State Road 91
State Road 91 (NM 91) is a state highway in the US state of New Mexico. Its total length is approximately . NM 91's northern terminus is at Interstate 40 Business/U.S. Route 54/ U.S. Route 84 (I-40 Bus./US 54/US 84) in Santa Rosa, and the southern terminus is southeast of Puerto De Luna where the state maintenance ends and it continues as County Road 2P towards US 84.
Eureka, California
U.S. Route 101 is the major north and south highway, which connects Eureka to the rest of the North Coast region. The highway connects to Oregon, located approximately to the north, and San Francisco, over to the south. The highway follows city streets through the city, with flow and cross-traffic controlled by traffic signals. Highway 101 enters Eureka from the south as Broadway. As it reaches the downtown area, it splits into a one-way couplet composed of 4th Street and 5th Street. On the north side of the city, northbound and southbound rejoin at the northeast side before the highway becomes a restricted (safety corridor) expressway (to Arcata and points beyond) as double bridges cross the Eureka Slough (mouth of the Freshwater Creek).
Oregon Route 241
Oregon Route 241 (OR 241) is an Oregon state highway running from U.S. Route 101 (US 101) in Coos Bay to Nesika County Park in Coos County. OR 241 is known as the Coos River Highway No. 241 (see Oregon highways and routes). It is long and runs east–west, entirely within Coos County.
U.S. Route 101 in Washington
Soon, US 101 turns north towards Raymond. In Raymond, US 101 intersects the western end of SR 6 and southern end of SR 105, which it will intersect again in Cosmopolis.
Connecticut Route 101
Route 101 starts at U.S. Route 44 as Mashamoquet Road then Killingly Road in the town of Pomfret. It runs along the Mashamoquet Brook State Park before intersecting with Route 169. It proceeds eastward, soon passing over the Quinebaug River into the town of Killingly. East of the river, the road becomes known as Hartford Pike. Route 101 then intersects Interstate 395 and Route 12, then passes near Chase Pond, a small pond related to the Chase Reservoir. Route 101 then passes between two large lakes; on the north, the Middle Reservoir (also known as the Chestnut Hill Reservoir), and on the south, the Bog Meadow Pond. It passes by more reservoirs, as it reaches its end at the Connecticut Rhode Island border. Route 101 continues in Rhode Island as Rhode Island Route 101.
Quebec Route 101
Route 101 is a highway in northwestern Quebec running in a north to south direction.
Ontario Highway 101
Approaching Chapleau, Highway 101 encounters Highway 129, onto which it turns northward and becomes concurrent for . Prior to entering the town, Highway 101 branches eastward, passing north of Chapleau Airport and resuming its course through the wilderness. Midway between Chapleau and Timmins, the route passes the village of Foleyet. It briefly travels through Timiskaming District before entering Cochrane District, through which the remainder of the route passes. After entering the city of Timmins, and approximately east of Highway 129, the route meets Highway 144, which travels south to Sudbury. Although classified as a city, very little of Timmins is developed, with the urban portion located in the centre of the city. Through the urban portion, Highway 101 is not maintained as a provincial highway and is a local road. This discontinuity begins just east of Kamiskotia Road and continues for to Gervais Street North.
East of Gervais Street North, Highway 101 travels northeast to Hoyle, passing beside several large open pit mines on the outskirts of Timmins. It then turn east and crosses the Frederick House River on the northern shores of Night Hawk Lake. The route passes through the only agricultural area along its journey, travelling straight for the remainder of the distance to Highway 11 west of Matheson. After a concurrency with Highway 11, Highway 101 branches north into Matheson, where it crosses the Abitibi River before curving east. Returning to wilderness, the route zig-zags towards the Ontario–Quebec border near Rouyn-Noranda, travelling several kilometres south of Lake Abitibi. The roadway continues eastward as Quebec Route 388 into the Abitibi-Témiscamingue region. With the exception of an undivided urban four lane section through Timmins, from Government Road in Mountjoy to Gervais Road South in Porcupine, the entire highway is two lanes wide.
New Brunswick Route 101
Route 101 is 76 kilometres long and runs from downtown Fredericton to a junction with Route 7 in Welsford.
Arcata, California
U.S. Route 101 extends north and south and bisects the city. The downtown has several overcrossings; Arcata is considered a fairly walkable community. State Route 299 connects to U.S. Route 101 at the northern end of Arcata. SR 299 begins at this point and extends easterly towards Weaverville, Redding, Alturas, and Nevada. SR 255 Connects to U.S. Route 101 at the southern end of Arcata on Samoa Blvd. and to the west of US-101 passes through Manila. Bridge access (left at first controlled intersection) leads to Eureka through Woodley island and Indian island (using three bridges) ending on 4th (south 101) and 5th (north 101) streets in Eureka, CA. Used as an alternate route to the US-101, its speed limit is though, unlike the speed on Highway 101 – which from the Bayside cutoff to Gallagher lane north 101 and x street south 101 is due to a safety corridor.
U.S. Route 101 in California
After merging with westbound traffic from the San Bernardino Freeway (I-10), US 101 then proceeds northwest via the Downtown Slot under the northern edge of Los Angeles' Civic Center to State Route 110 (SR 110) at the Four Level Interchange. From here, US 101 becomes the Hollywood Freeway. It then heads to Hollywood and up through the Cahuenga Pass before reaching the San Fernando Valley.
U.S. Route 201
U.S. Route 201 (US 201) is part of the nationwide system of United States Numbered Highways. It runs for entirely within the state of Maine and is a spur route of U.S. Route 1. Its southern terminus is in Brunswick at US 1 and Maine State Route 24 Business. Its northern terminus is at the Canada–US border near Jackman (a terminus it shares with Maine State Route 6), where it connects to Quebec Route 173.
Ohio State Route 101
Near the southern city limits of Sandusky, SR 101 formerly traveled on a straight line along Tiffin Avenue where it began a concurrency with US 6 at Venice Road and Sanford Street. Because of long-time concerns about a grade crossing with the Norfolk Southern railroad at Tiffin Street and nearby Venice Street (which carried US 6 at the time). The project to realign the two highways began in 2010 and was completed four years later. , the former alignment of SR 101 is designated SR 101-J (with former alignments of Venice Road being designated US 6-C and US 6-J); the "J" suffix meant that the route is awaiting abandonment by the Ohio Department of Transportation.
U.S. Route 101 in Oregon
The stretch of US 101 through Lincoln City is infamous for its clogged traffic; the city is over seven miles (11 km) long (but only a few blocks wide in spots), and is sandwiched between the ocean on the west, and Devils Lake and mountains to the east. In many parts of town, the highway is a two-lane road. Adding to the traffic is a casino in the northern part of town. Much of the traffic departs US 101 north of Lincoln City, at an interchange with Oregon Route 18.
Utah State Route 101
State Route 101 (SR-101) is a long state highway located in the U.S. state of Utah. The route serves as a spur route into the Uinta-Wasatch-Cache National Forest through the cities of Wellsville and Hyrum, with an intermediate intersection with U.S. Route 89 (US-89) and US-91. SR-101 starts at an intersection of Main Street and SR-23 (Center Street) in Wellsville. Heading generally eastward, the highway terminates at the Hardware Ranch Wildlife Management Area. SR-101 was first designated in 1931 as a loop off SR-1 from Logan, south to Hyrum, and west to Wellsville.
U.S. Route 191
U.S. Route 191 (US 191) is a spur of U.S. Route 91 that has two branches. The southern branch runs for from Douglas, Arizona on the Mexican border to the southern part of Yellowstone National Park. The northern branch runs for from the northern part of Yellowstone National Park to Loring, Montana, at the Canada–US border. Unnumbered roads within Yellowstone National Park connect the two branches. The highway passes through the states of Arizona, Utah, Wyoming, and Montana.
Louisiana Highway 101
Louisiana Highway 101 (LA 101) is a state highway located in southwestern Louisiana. It runs in a general north–south direction from LA 14 in Hayes to LA 383 north of Iowa.
West Virginia Route 101
West Virginia Route 101 is an unsigned long north–south state highway in the City of Huntington in Cabell County, West Virginia. The southern terminus of the route is at U.S. Route 60 (31st Street). The northern terminus is at US 60 (Third Avenue).
Louisiana Highway 101
In the original Louisiana Highway system in use between 1921 and 1955, the modern LA 101 made up parts of several routes, including State Route 1156 from Hayes to Lacassine; State Route 728 from Lacassine to the curve east of Woodlawn; State Route 744 from the curve to Woodlawn; and State Route 24-D west of Woodlawn. The first three were additions to the state highway system in 1930. The last, Route 24-D, indicates an earlier alignment of State Route 24, which was one of the original 98 state highways created in 1921. In 1926, Route 24 was selected to carry the southern portion of US 165 when the numbered U.S. Highway system was implemented. The portion of what is now LA 101 west of Woodlawn was therefore a small part of the original alignment of US 165 until the present alignment alongside the Missouri Pacific Railroad (now the Union Pacific Railroad) line was completed in 1939.
U.S. Route 701
US 701 has a length of in South Carolina and spans in North Carolina. The U.S. Highway is a part of the National Highway System for one short stretches during its concurrency with NC 24 in Clinton.
U.S. Route 141
US Highway 141 (US 141) is a north–south United States Numbered Highway in the states of Wisconsin and Michigan. The highway runs north-northwesterly from an interchange with Interstate 43 (I-43) in Bellevue, Wisconsin, near Green Bay, to a junction with US 41/M-28 near Covington, Michigan. In between, it follows city streets in Green Bay and has a concurrent section with US 41 in Wisconsin. North of Green Bay, US 141 is either a freeway or an expressway into rural northern Wisconsin before downgrading to an undivided highway. In Michigan, US 141 is an undivided highway that runs through rural woodlands. The highway has two segments in each state; after running through Wisconsin for about , it crosses into Michigan for approximately another . After that, it crosses back into Wisconsin for about before crossing the state line one last time. The northernmost Michigan section is about , making the overall length about .
Indiana State Road 101
The second portion of SR 101 is long and is within Ripley County. This sections of SR 101 begins at U.S. Route 50 (US 50) and heads north towards Milan. The road passes through rural farmland with a few houses as a two-lane highway. The road turns towards the northeast just south of SR 48. After SR 48 the highway turns back due north. This section ends at an interchange with Interstate 74 (I–74) in Penntown.
Santa Maria, California
U.S. Route 101 runs through the middle of the Santa Maria Valley and is the main freeway connecting many west coast cities. It has been improved to freeway status (meaning all at-grade intersections have been eliminated) within the city of Santa Maria itself. There was recently a widening project that expanded the freeway from four to six lanes between Santa Maria Way and the highway 166 exit. The $32 million project was completed in late 2008 / early 2009.
New Jersey Route 81
Route 81 is a state highway in the U.S. state of New Jersey. The route is a freeway connector between exit 13A of the New Jersey Turnpike (Interstate 95) and U.S. Route 1/9 near Newark Liberty International Airport. It runs for 1.18 miles (1.90 km), entirely within the city of Elizabeth in Union County. A freeway called Route S100 was initially proposed on the current alignment of Route 81 in 1938; it, along with its parent Route 100, was never built. The current route was conceived in the 1960s as a freeway replacement for Route 164, which followed Humboldt Avenue, a surface road. It was to be designated Route 76, but was renumbered to Route 81 when Interstate 76 was created in New Jersey.
U.S. Route 101 in California
US 101 then intersects with SR 134 and SR 170 at the interchange known as the Hollywood Split. Here, the alignment of US 101 shifts to the alignment of SR 134 (i.e. heading northbound, the road's alignment turns left, or westbound) and thereafter is referred to as the Ventura Freeway until it reaches Ventura. Though confusing, the "Hollywood Freeway" name continues northward from this interchange on SR 170, and the "Ventura Freeway" name continues eastward to SR 134.
U.S. Route 141
In 1986, the states in the Great Lakes region created the LMCT as part of a larger program of tourist routes in the region; US 141 carries the LMCT between the northern I-43 junction in the Green Bay area north to the split with US 41 at Abrams. In the first years of the 21st century, US 141 was expanded to a four-lane expressway northward from Abrams to Oconto Falls. A further upgrade in 2006 expanded the highway to four-lanes northward to Beaver. On April 7, 2015, the segment of US 141 that runs concurrently with US 41 on the west side of Green Bay designated a part of I-41 by the Federal Highway Administration.
Gaviota Peak
Gaviota Grade, is the most formidable in length and elevation change along U.S. Route 101 in Southern California.
U.S. Route 81
Its southern terminus is in Fort Worth, Texas, at an intersection with Interstate 35W. Between the inception of the numbered highway system in 1926 through 1991, US 81's southern terminus was at the Mexican border in Laredo, Texas. In 1991, the terminus was moved to San Antonio. The route was shortened to its present length of in 1993, when the terminus was moved to Fort Worth. In both cases, the dropped portions of US 81 were replaced by Interstate 35. Portions of former US-81 south of Fort Worth continue to exist as business loops of I-35; a section from Hillsboro to Fort Worth exists as State Highway 81.
U.S. Route 101 in California
From the Hollywood Split, US 101 is an east–west highway (until it reaches Gaviota State Park in Santa Barbara County where it shifts back to a north–south alignment). It meets with I-405 in Sherman Oaks, an interchange which holds claim to the most traveled intersection in the nation. The east–west geographical alignment of the Ventura Freeway and the north–south designation which appears on the freeway signs can be confusing to visitors; the same freeway entrance can often be signed as "101 North" and "101 West"; this is most common in the San Fernando Valley where the local E/W signing does not match the Caltrans' proper statewide N/S designation.
Arkansas Highway 101
Highway 101 begins at an overlap between US 62/US 412 east of Mountain Home near Lake Norfork. The route passes the Panther Bay Public Use Area, the Bidwell Point Use Area, and the Seward Point Public Use Area. Highway  continues north through the community of Gamaliel before crossing into Missouri where the roadway continues as Route 101. The average daily traffic counts from the Arkansas State Highway and Transportation Department (AHTD) for 2010 show that a maximum of about 2800 vehicles per day (VPD) use the northern portion of Highway 101, with the count dropping to around 1500 VPD for portions further south.
U.S. Route 191
The highway was designated in 1926 and its routing has changed drastically through the years. The modern US 191 bears almost no resemblance to the original route, which was primarily in the state of Idaho. Most of the current route of US 191 was formed in 1981. Since the extensions in the 1980s and 1990s, U.S. Route 191 is much longer than its parent route which it no longer connects to, and one of the longest U.S. three-digit routes.
Special routes of U.S. Route 101
US 101 Business, called Central Ave its entirety, is a business loop of
US 101 through McKinleyville.
U.S. Route 101 Business is a business loop of US 101 that travels from Astoria to Warrenton. It is a former alignment of US 101, bypassed in 1964 when a new bridge opened across Youngs Bay. It was originally designated U.S. Route 101 Alternate until about 1976.
Texas State Highway 101
SH 101 was previously designated on February 17, 1925 on a route from Snyder to Colorado City. Another route from Georgetown east to SH 95 at Circleville was also designated on May 4, 1925. On March 18, 1927, the SH 101 from Georgetown to Circleville was renumbered as SH 104. As a result, there was only one SH 101 from Snyder to Colorado City. On November 30, 1932, SH 101 extended south to Sterling City. By 1936, the route was complete from Snyder to Colorado City, but was still an earthen road. By 1939, it was completed, with a terminus just west of Sterling City. The section north of Colorado City was transferred to SH 208 on February 23, 1956, with the remaining portion of the route cancelled and transferred to the northern extension of SH 163 on September 27, 1957. The current route was designated on its current path on November 25, 1975 to replace US 81 and US 287, which were routed onto a new built upgraded parallel path, and State Highway 114, which was moved to a different routing in the state.
Utah State Route 101
Located entirely in Cache County, SR-101 starts at an intersection of Main Street and SR-23 (Center Street) in Wellsville. The highway heads easterly for the first before it turns northeasterly, crossing the Little Bear River and intersects US-89/US-91 at a traffic light controlled at-grade interchange. After the interchange, SR-101 turns to the southeast after entering Hyrum city limits. At 400 West, SR-101 turns south for 3 blocks before turning back to the east, and intersecting SR-165.
U.S. Route 101 in Oregon
North of Coos Bay, the highway runs along the eastern flank of the Oregon Dunes National Recreation Area, through the communities of Hauser, Lakeside, and Winchester Bay before coming into the city of Reedsport on the mouth of the Umpqua River. The highway continues north from there, passing through the dunes and through the towns of Gardiner, Westlake, Dunes City, and Glenada. The next major town is Florence on the Siuslaw River.
U.S. Route 301 in Maryland
Originally, the route went all the way along former MD 3 into Baltimore and ended near present-day Maryland Route 295 Russell Street. As US 301, it was upgraded into a four- and six-lane divided highway throughout in the 1940s and 1950s. In the 1960s, the route was rerouted along US 50 to the Eastern Shore where it split from US 50 and was routed from there up former Maryland Route 71 into Delaware. Today, Route 301 is a multi-lane highway throughout its path through the state with the exception of the Governor Harry W. Nice Memorial Bridge; the nine miles (14 km) of MD 3 between US 50 and Interstate 97 is also a four- and six-lane divided highway and is part of the same continuous physical route.
South Carolina Highway 101
South Carolina Highway 101 (abbreviated SC 101) is a state route in Laurens, Spartanburg, and Greenville counties. Its southern terminus is at a junction with U.S. Route 76 (US 76) in Hickory Tavern, and its northern terminus is at a junction with SC 11 near Landrum.
U.S. Route 81
U.S. Route 81 is a major north-south highway that extends for 1220 miles in the central United States and is one of the earliest United States Numbered Highways established in 1926 by the US Department of Agriculture Bureau of Public Roads.
Arizona State Route 101
Arizona State Route 101, or Loop 101, (spoken as one-oh-one) is a semi-beltway encompassing much of the Phoenix Metropolitan Area in the United States. It connects several suburbs of Phoenix, including Tolleson, Glendale, Peoria, Scottsdale, Mesa, Tempe, and Chandler. Construction began in the late-1980s and was completed in 2001.
Additional general purpose lanes and a high occupancy vehicle lane (HOV) are being constructed along the eastern stretch of Loop 101 from Scottsdale to Chandler, starting at Princess Drive to Loop 202 (the Santan Freeway).
U.S. Route 101
Entering Washington State at the north end of the Astoria–Megler Bridge west of Megler at the intersection with SR 401, US 101 follows the northern banks of the Columbia River until Ilwaco. At this point it turns to the northeast and follows the shore of Willapa Bay and the Willapa River as far as Raymond, from which it proceeds directly north to Aberdeen, offering access from this city into the Olympic National Park. While the AAA has designated this segment north and then east to Port Angeles and Sequim as a scenic byway, some clear-cut logging in the early 1990s has diminished the scenic value of the highway where it crosses the Quinault Indian Reservation and the Olympic National Forest.
Georgia State Route 101
SR 101 begins at an interchange with Interstate 20 (I-20) in Villa Rica, in Carroll County, where SR 101 is concurrent with SR 61 for approximately north until they intersect US 78/SR 8. SR 61 splits off, while SR 101 travels northwest into Paulding County. The only major intersection in the county is with SR 113/SR 120 (Buchanan Highway), in the unincorporated community of Union. SR 101/SR 113 travel concurrently. In Polk County, the road meets US 278/SR 6, southeast of Rockmart. The four highways travel concurrent to the northwest, and enter Rockmart. They bypass the main part of town to the east, northeast, and north. On the northeast corner of the city, SR 113 splits off to the northeast. At Piedmont Avenue, SR 101 splits off to the north-northwest. This intersection also marks the eastern terminus of US 278 Bus./SR 6 Bus. SR 101 continues to the northwest and enters Floyd County. It curves to an almost-due-north orientation and enters Rome. In the city, it has an incomplete interchange with US 411 north/SR 20 east, just east of Georgia Northwestern Technical College; there is no access from SR 101 to US 411 south/SR 20 west. The route travels to the north and curves to the northwest to intersect US 27/SR 1/SR 53 (Turner McCall Boulevard). It crosses over the Etowah and Oostanaula rivers. It passes Barron Stadium and Floyd Medical Center, before it meets its northern terminus, an intersection with US 27/SR 1/SR 20, farther along in the city. SR 101 is not part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.
Alabama State Route 101
SR 101 begins at an intersection with CR 460 west of Moulton, in Lawrence County. This intersection is just west-southwest of Town Creek Cemetery. It travels to the north and intersects SR 24. It curves to the north-northwest and intersects the western terminus of CR 114. The highway intersects the northern terminus of CR 50 and curves to the north-northeast. It has a one-block concurrency with CR 128. SR 101 meets the northern terminus of CR 127. Then, it intersects the eastern terminus of CR 343. The highway curves to the northeast and intersects the western terminus of CR 157. It curves to a nearly due north direction and intersects the eastern terminus of CR 131. SR 101 enters Hatton. There, it passes Hatton High School and has a one-block concurrency with CR 236. Upon leaving Hatton, SR 101 intersects the western terminus of CR 156 and the southern terminus of CR 147, which are one block apart. The highway curves to the northwest and crosses over Watches Creek. After it curves to the north-northwest, it intersects the eastern terminus of CR 146. It then curves to the north-northeast and intersects SR 157 (University of North Alabama Highway). Then, it intersects CR 136. One block later is the eastern terminus of CR 255. The highway crosses over Beck Creek and intersects the western terminus of CR 589 just before curving back to the north-northwest. After curving to the northeast, it intersects the western terminus of CR 258 and then the eastern terminus of CR 259. At the beginning of a curve to the northwest is an intersection with the southern terminus of CR 262. The highway curves to the north-northeast and enters Town Creek. It crosses over Tucker Branch and intersects the eastern terminus of CR 143. Just before heading north, SR 101 intersects the northern terminus of CR 261 (Brooks Spring Road). It intersects the eastern terminus of CR 141 and the eastern terminus of CR 267. In the main part of Town Creek, is an intersection with US 72 Alt./SR 20 and a crossing of Warren Branch. Just before leaving the city limits of Town Creek, the highway intersects the southern terminus of CR 216. It crosses over Meadow Branch. It then intersects the western terminus of CR 269 and the eastern terminus of CR 268 before meeting CR 406. After an intersection with the eastern terminus of CR 404, SR 101 passes Mathews Cemetery. It then intersects the eastern terminus of SR 184 and the northern terminus of CR 270 before reaching CR 314 (Foster Mill Road). SR 101 curves to the northeast and crosses over Big Nance Creek. Immediately after that crossing, it travels through the southern and southeastern parts of Joe Wheeler State Park. Just before leaving the park, it intersects CR 150 and CR 414 in close succession. The highway curves to the north-northwest and travels through Wheeler Dam Village. It then crosses over the Tennessee River on top of Wheeler Dam. This crossing marks the Lauderdale County line.
Utah State Route 101
SR-101 was formed in 1931 as a loop off SR-1 (now US-91) from Logan south to Hyrum and west to Wellsville. The road from Hyrum east to the Hardware Ranch was added to the state highway system in 1949 as State Route 242, and that route was extended south to SR-39 in 1965. The legislature redefined the Hyrum-area routes in 1969, taking SR-101 east from Wellsville to the Hardware Ranch over former SR-242, and returning the extension to SR-39 to local control. The leg of former SR-101 from Hyrum north to Logan became part of a new SR-165 at that time. On March 17, 1972, the roadway connecting the Hardware Ranch Visitors Center to SR-101 was added to the state route system as an addition to SR-101. The connector road was previously designated Collector Road 311.
Rhode Island Route 101

Maine State Route 101
State Route 101 (SR 101) is a short state highway in extreme southern Maine. It follows a southeast–northwest trajectory, signed as south–north. SR 101 begins at an intersection with U.S. Route 1 (US 1) in Kittery, and runs northwest to the New Hampshire state line, where it continues as Gulf Road, an unnumbered local road in Dover towards New Hampshire Route 4.
U.S. Route 101 in Washington
From Ilwaco, US 101 travels northwest into Seaview, where it intersects SR 103 at the foot of Long Beach and turns east onto 40th Street. The highway intersects the north end of the alternate route and crosses northeast over the Bear River and enters the Willapa National Wildlife Refuge. US 101 continues north along the east side of Willapa Bay and crosses the Naselle River before turning east towards Johnston's Landing, where SR 4 terminates.
U.S. Route 101 in California
The south terminus of US 101 is in Los Angeles, about east of downtown Los Angeles at the East Los Angeles Interchange, also known as the "Commuters' Complex". This southernmost portion is named the Santa Ana Freeway, inheriting that title as the northerly extension of the roadway now known as I-5.
U.S. Route 101 in California
North of the town of Klamath just inside Del Norte County, the highway closely follows the Pacific coast again. In Crescent City, US 101 once again separates into a one-way couplet (L and M Streets) for nine blocks. As it leaves Crescent City, US 101 becomes a divided freeway for the last time in California (built slightly to the west of the original two-lane alignment, now called Parkway Drive). As the 3-mile divided freeway portion ends, US 101 intersects the southern terminus of US 199, which heads northeast as the Redwood Highway, passing through the Collier Tunnel and terminating in Grants Pass, Oregon. US 101 (no longer called the "Redwood Highway" at this point) is reduced to two lanes and continues north along the California coast until it reaches the Oregon border.
Connecticut Route 101
In 1922, Connecticut numbered its state highways. The turnpike from Phoenixville to west of Pomfret Landing was designated as part of Route 101. The original Route 101 began in South Chaplin, where it split off from New England Route 3. It ran northward via modern Route 198 to Phoenixville then turned eastward along the Connecticut and Rhode Island Turnpike (modern Route 44) to west of Pomfret Landing. Route 101 then continued along modern Route 44 northward to Pomfret Center and eastward through Putnam to the Rhode Island line. Route 101 followed modern Route 44 through Rhode Island all the way to Plymouth, Massachusetts. At the same time, the eastern half of the Connecticut and Rhode Island Turnpike was designated as Highway 137 west of Route 12 and Highway 139 east of Route 12.
Special routes of U.S. Route 101
A total of fifteen special routes of U.S. Route 101 exist.
Present SR 1 in the Los Angeles area was U.S. Route 101 Alternate from the mid-1930s to 1964.
The precursor to the Santa Ana Freeway between Los Angeles and Anaheim was U.S. Route 101 Bypass from the early 1940s to the mid-1950s, when it became part of US 101. Old US 101 there is now partially SR 72.
U.S. Route 441
U.S. Route 441 is a spur route of U.S. Route 41. It runs for 939 miles (1,511 km) from U.S. Route 41 in Miami, Florida to U.S. Route 25W in Rocky Top, Tennessee. Between its termini, US 441 passes through the states of Florida, Georgia, North Carolina and Tennessee. The route acts as a connector between several major urban areas, including Miami, Orlando, Ocala, Gainesville, Athens and Knoxville. It also crosses the Great Smoky Mountains National Park, where it meets the southwestern end of the Blue Ridge Parkway, and where no trucks or other commercial traffic are allowed.
U.S. Route 101 in California
Instead of terminating in Los Angeles, US 101 once continued all the way south through San Diego to the United States–Mexico border in San Ysidro. However, this part was decommissioned on July 1, 1964, in favor of I-5. The only remnant of the old route on US 101's current alignment is a mileage sign at the Santa Barbara–Ventura county line, which lists the distance to San Diego, even though US 101 ends in Los Angeles.
