What's the longest highway in the US?
U.S. Route 20
U.S. Highway 20 (US 20) is an east–west United States highway that stretches from the Pacific Northwest all the way to New England. The "0" in its route number indicates that US 20 is a coast-to-coast route. Spanning , it is the longest road in the United States, and particularly from Newport, Oregon to Boston, Massachusetts, the route is roughly parallel to that of the newer Interstate 90 (I-90), which is in turn the longest Interstate Highway in the U.S. There is a discontinuity in the official designation of US 20 through Yellowstone National Park, with unnumbered roads used to traverse the park.
U.S. Route 20 in Massachusetts
U.S. Route 20 is the longest numbered highway in the entire country and also holds the distinction of being the longest numbered highway in the state, edging out Route 28 by merely a mile (Route 28 is long).
South Carolina Highway 9
South Carolina Highway 9 (SC 9) is a major state highway in the U.S. state of South Carolina. The route runs from North Myrtle Beach to the North Carolina border upstate. The road is currently the longest state highway in South Carolina. It is signed as a north–south highway (with North Myrtle Beach as its southern terminus and the North Carolina border as its northern) though overall it runs in an east–west direction.
Maine State Route 11
At just over , SR 11 is the longest state highway in Maine, and the second longest numbered highway in the entire state (behind US 1, which runs just over in Maine). It is almost longer than Maine's longest Interstate Highway, its section of Interstate 95 (I-95). Overall, Route 11 in Maine, New Hampshire, and Vermont are long.
Transportation in Appalachia
The next great leap in transportation was the creation of the U.S. Highway system in 1926, replacing the auto trails. The longest primary US highway contained in Appalachia is US 11 traversing the eastern side. US 21 was another primary US highway, but much of its route has been decommissioned and replaced with Interstate 77. These make/made up the north-south routes. East-west routes include US 30, US 33, US 40, US 50, US 60, and US 70. Many spur routes such as US 220 and US 119 serve various parts of Appalachia.
U.S. Route 64
Overall, US 64 runs from the Western edge of the state to the Outer Banks. It is the longest highway in North Carolina. In North Carolina, the common way to express coverage of the entire state is to say, "from Manteo to Murphy." US 64 runs through both.
U.S. Route 34
U.S. Route 34 is an east–west United States highway that runs for from north-central Colorado to the western suburbs of Chicago. Through Rocky Mountain National Park it is known as the Trail Ridge Road where it reaches elevation , making it the highest paved through highway in the United States. The highway's western terminus is Granby, Colorado at U.S. Route 40. Its eastern terminus is in Berwyn, Illinois at Illinois Route 43 and Historic US 66.
Transportation in the United States
Nearly all railroad corridors (not including local transit rail systems) are owned by private companies that provide freight service. Amtrak pays these companies for the right to use the tracks for passenger service. There are approximately 150,000 mi (240,000 km) of mainline track in the United States—the world's longest national railroad network. "See List of United States railroads"
Harlem Avenue
Harlem Avenue is a major north-south street in Chicago, Illinois, United States and the west/southwest/northwest suburbs. It stretches from Glenview Road in Glenview to the intersection of E. South Street and S. Drecksler Road in Peotone, where it divulges into IL Route 50. At 54.1 miles it is the third-longest street in the United States, after Telegraph Road in southeastern Michigan and O Street in Nebraska. For most of its length it carries Illinois Route 43. There is a stop along the Metra BNSF Line at Harlem Avenue and Windsor Avenue in Berwyn, Illinois.
List of Interstate Highways in Illinois
The Interstate Highways in Illinois are all segments of the Interstate Highway System that are owned and maintained by the U.S. state of Illinois. The Illinois Department of Transportation (IDOT) is responsible for maintaining these highways in Illinois. The Interstate Highway System in Illinois consists of 13 primary highways and 11 auxiliary highways which cover . The Interstate Highway with the longest section in Illinois is Interstate 57 at ; the shortest is Interstate 41 at .
Sioux City, Iowa
Interstate 29 is a major controlled-access highway in Sioux City and the surrounding area providing easy access of the 20 mile stretch covering Sioux City and the majority of its suburbs. It approaches the city from Omaha to the south before curving northwest along the Missouri River near downtown. The highway then enters South Dakota and curves back to the north as it approaches Sioux Falls. Interstate 129 is an auxiliary Interstate that connects South Sioux City, Nebraska to the south side of Sioux City and works as a bypass for travelers to other surrounding suburbs. Interstate 129 also interconnects with U.S. Route 75 which is in expansion to expressway form connecting Sioux City to Worthington, Minnesota. U.S. Route 20, the longest road in the United States spanning is also in the works of expanding from a two-lane highway to four-lanes from Sioux City to Dubuque, Iowa which will provide faster and easier access comparable to Interstate 80 in Iowa. Sioux City operates automatic speed cameras on interstate highways. The cameras are operated by Redflex Holdings and are reported to provide approximately $4.5 million per year for the city budget. The state of South Dakota has been refusing to provide addresses associated with licence plates due to the large number of South Dakota residents fined by Sioux City.
Pennsylvania
The Pennsylvania Department of Transportation, abbreviated as PennDOT, owns of the of roadway in the state, making it the fifth-largest state highway system in the United States. The Pennsylvania Turnpike system is long, with the mainline portion stretching from Ohio to Philadelphia and New Jersey. It is overseen by the Pennsylvania Turnpike Commission. Another major east–west route is Interstate 80, which runs primarily in the northern tier of the state from Ohio to New Jersey at the Delaware Water Gap. Interstate 90 travels the relatively short distance between Ohio and New York through Erie County, in the extreme northwestern part of the state.
Primary north–south highways are Interstate 79 from its terminus in Erie through Pittsburgh to West Virginia, Interstate 81 from New York through Scranton, Lackawanna County and Harrisburg to Maryland and Interstate 476, which begins north of the Delaware border, in Chester, Delaware County and travels to Clarks Summit, Lackawanna County, where it joins I-81. All but of I-476 is the Northeast Extension of the Pennsylvania Turnpike, while the highway south of the main line of the Pennsylvania Turnpike is officially called the "Veterans Memorial Highway", but is commonly referred to by locals as the "Blue Route".
Interstate 90
I-39/90/94 from just south of Portage to Madison is the longest concurrency of three Interstate Highways in the United States.
List of Interstate Highways in Michigan
The Interstate Highways in Michigan are the segments of the national Dwight D. Eisenhower System of Interstate and Defense Highways that are owned and maintained by the U.S. state of Michigan, totaling about . The longest of these, Interstate 75 (I-75), is also the longest highway of any kind in the state. On a national level, the standards and numbering for the system are handled by the Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO), while the highways in Michigan are maintained by the Michigan Department of Transportation (MDOT) and the Mackinac Bridge Authority (MBA). The Interstates in Michigan have their origins in World War II-era expressways built in the Detroit area. After the system was created in 1956, the state highway department completed its first border-to-border Interstate in 1960. The last highway was completed in 1992, giving Michigan a total of 13 Interstate freeways. The original allotment of mileage to Michigan which would receive federal funding was expanded in 1968, and the United States Congress designated an additional highway in the 1990s that has not yet been built.
Highway systems by country
Arguably, the most famous United States highway is U.S. Route 66. It is immortalized in the song "(Get Your Kicks On) Route 66", and by the legendary TV series "Route 66". Other famous highways in songs include Highway 61 (Bob Dylan, 1965), Carefree Highway in Arizona (Gordon Lightfoot, 1974), Colorado Boulevard in Pasadena, California (Jan & Dean, also Beach Boys, 1964), the song "Ventura Highway", named for a highway in Southern California ("America", 1972), and Blues Highway in Mississippi (Fred McDowell, 1959).
Interstate 80
Interstate 80 (I-80) is an east–west transcontinental freeway in the United States that runs from downtown San Francisco, California, to Teaneck, New Jersey, in the New York City Metropolitan Area. The highway was designated in 1956 as one of the original routes of the Interstate Highway System. Its final segment was opened to traffic in 1986. It is the second-longest Interstate Highway in the United States, following I-90. The Interstate runs through many major cities including Oakland, Sacramento, Reno, Salt Lake City, Omaha, Des Moines, and Toledo, and passes within of Chicago, Cleveland, and New York City.
New York State Thruway
The New York State Thruway system is a collection of six individual components across the state of New York that connect the state to four neighboring states (Connecticut, Massachusetts, New Jersey, and Pennsylvania) as well as the Canadian province of Ontario. Together, the highways extend for , making the Thruway system one of the largest toll highway systems in the United States. The longest of the six components is the mainline. Of the 570 miles in the Thruway system, (98.4%) carries at least one Interstate Highway designation. Only three sections of the system are not part of the Interstate Highway System; these are the Garden State Parkway Connector in Rockland County, a portion of the Berkshire Connector between its western terminus at exit 21A on the mainline near Selkirk and where it joins up with Interstate 90 at exit B1 near Castleton-on-Hudson, and a short section of the mainline within exit 24 in Albany that is located between where I-87 departs the roadway and I-90 enters it. They are designated as New York State Route 982L (NY 982L), NY 912M, and NY 915H, respectively, all unsigned reference routes. The speed limit, enforced by the New York State Police, is 65 miles per hour along most of the Thruway.
Historic roads and trails
In the American Old West, the Oregon Trail was a 19th-century pioneer route from Illinois to Oregon. The Santa Fe Trail was a major commercial and military artery from Missouri to Santa Fe, New Mexico.
In modern times, the Lincoln Highway (dedicated 1913) was the first road for the automobile across the United States of America, spanning 3389 miles coast-to-coast from New York City to San Francisco.
Arkansas Highway System
The Arkansas Highway System is made up of all the highways designated as Interstates, U.S. Highways and State Highways in the US state of Arkansas. The system is maintained by the Arkansas Department of Transportation (ArDOT), known as the Arkansas State Highway Department (AHD) until 1977 and the Arkansas State Highway and Transportation Department (AHTD) from 1977 to 2017. The system contains of Interstates, U.S. Routes, state highways, and special routes. The shortest members are unsigned state highways Arkansas Highway 806 and Arkansas Highway 885, both in length. The longest route is U.S. Route 67, which runs from Texarkana to Missouri.
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.
Texas state highway system
In 1992, the of Interstate Highway System in Texas was completed with the opening of a section of I-27. In 1997, the Texas Turnpike Authority was merged with TxDOT and independently, the North Texas Turnpike Authority became responsible for toll projects in Collin, Dallas, Denton, and Tarrant counties.
The Interstate Highway System in Texas covers and consists of ten primary highways, seven auxiliary highways, and the splitting of both Interstate 35 (I-35) and Interstate 69 into multiple letter-suffixed branches. The Interstate Highway with the longest segment in Texas is I-10 at . The shortest in the state is I-110 at .
U.S. Route 40
U.S. Route 40 (US 40), also known as the Main Street of America, is an east–west United States Highway. As with most routes whose numbers end in a zero, US 40 once traversed the entire United States. It is one of the first U.S. Highways created in 1926 and its original termini were in San Francisco, California and Atlantic City, New Jersey. In the western United States, US 40 was functionally replaced by Interstate 80 (I-80), resulting in the route being truncated multiple times. US 40 currently ends at a junction with I-80 in Silver Summit, Utah, just outside Park City.
Interstate Highway System
The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, is a network of controlled-access highways that forms part of the National Highway System in the United States. The system is named for President Dwight D. Eisenhower, who championed its formation. Construction was authorized by the Federal Aid Highway Act of 1956, and the original portion was completed 35 years later, although some urban routes were cancelled and never built. The network has since been extended. In 2016, it had a total length of . , about one-quarter of all vehicle miles driven in the country use the Interstate system. In 2006, the cost of construction was estimated at about $425 billion (equivalent to $ in ).
California
The state has been a pioneer in road construction. One of the state's more visible landmarks, the Golden Gate Bridge, was the longest suspension bridge main span in the world at between 1937 (when it opened) and 1964. With its orange paint and panoramic views of the bay, this highway bridge is a popular tourist attraction and also accommodates pedestrians and bicyclists. The San Francisco–Oakland Bay Bridge (often abbreviated the "Bay Bridge"), completed in 1936, transports about 280,000 vehicles per day on two-decks. Its two sections meet at Yerba Buena Island through the world's largest diameter transportation bore tunnel, at wide by high. The Arroyo Seco Parkway, connecting Los Angeles and Pasadena, opened in 1940 as the first freeway in the Western United States. It was later extended south to the Four Level Interchange in downtown Los Angeles, regarded as the first stack interchange ever built.
Interstate 5 in Oregon
Interstate 5 is the second-longest freeway in Oregon, at , and is the only Interstate to traverse the state from north to south. The highway connects several of the state's largest metropolitan areas, which lie in the Rogue and Willamette valleys, and passes through counties with approximately 81 percent of Oregon's population. As a component of the Interstate Highway System, I-5 is also designated as an important highway under the National Highway System. It is officially designated under Oregon's named route system as the Pacific Highway No. 1, a name shared with Oregon Route 99 (OR 99) and its split routes north of Junction City. OR 99 runs concurrent to I-5 through most of southern Oregon, splitting from the freeway to serve city centers and use other alternate routes, while OR 99W and OR 99E serve corridors on opposite sides of the Willamette River. The state legislature also designated I-5 as the Purple Heart Trail and Korean War Veterans Memorial Highway in 2015.
Interstate 495 (Massachusetts)
Interstate 495 (I-495) is an auxiliary route of I-95 in the U.S. state of Massachusetts, maintained by the Massachusetts Department of Transportation (MassDOT). Spanning , it is the second-longest auxiliary route in the Interstate Highway System, ranking behind I-476 in Pennsylvania by a difference of roughly .
List of U.S. Highways in Maryland
The following is a list of U.S. Highways in Maryland. There are currently 14 U.S. Highways that exist entirely or partially in the U.S. state of Maryland. Seven of these are primary U.S. Highways while seven are auxiliary U.S. Highways that may or may not be related to one of the primary U.S. Highways. The longest primary U.S. Highway in Maryland is U.S. Route 40 (commonly abbreviated US 40) at . The shortest primary U.S. Highway in Maryland is US 11 at . The longest auxiliary U.S. Highway in Maryland is US 301 at . The shortest auxiliary U.S. Highway in Maryland is US 522 at . All U.S. Highways are maintained by the Maryland State Highway Administration except for the portions that run through Baltimore, Hagerstown, and Cumberland. Maryland has five former U.S. Highways; those five are shaded in dark gray in the list.
Louisiana Highway 1 Bridge
The Louisiana Highway 1 Bridge, also known as the Gateway to the Gulf Expressway, is a concrete trestle toll bridge in the U.S. state of Louisiana. With a total length of 13,300 m or 43,600 ft (8 miles), it is one of the longest bridges in the world.
Interstate 70 in Colorado
The U.S. Department of Transportation (USDOT) lists the construction of I-70 among the engineering marvels undertaken in the Interstate Highway system, and cites four major accomplishments: the section through the Dakota Hogback, Eisenhower Tunnel, Vail Pass and Glenwood Canyon. The Eisenhower Tunnel, with a maximum elevation of and length of , is the longest mountain tunnel and highest point along the Interstate Highway System. The portion through Glenwood Canyon was completed on October 14, 1992. This was one of the final pieces of the Interstate Highway System to open to traffic, and is one of the most expensive rural highways per mile built in the United States. The Colorado Department of Transportation (CDOT) earned the 1993 Outstanding Civil Engineering Achievement Award from the American Society of Civil Engineers for the completion of I-70 through the canyon.
Montana Highway 200
Montana Highway 200 (MT 200) in the U.S. state of Montana is a route running east-west covering the entire state of Montana. From the starting point at ID 200, near Heron, Montana the highway runs east to ND 200 near Fairview, Montana. It is part of a chain of state highways numbered "200" which extend from Idaho across Montana, North Dakota and Minnesota. Montana Highway 200 is also the longest route signed as a state highway in the United States.
Highway 200 helps to connect many small towns located in central Montana and the vast plains area of eastern Montana, to larger western Montana cities such as Great Falls and Missoula.
U.S. Route 1
U.S. Route 1 (US 1) is a major north–south U.S. Highway that serves the East Coast of the United States. It runs , from Key West, Florida north to Fort Kent, Maine, at the Canada–US border, making it the longest north–south road in the United States. US 1 is generally paralleled by I-95, though the former is significantly farther west (inland) between Jacksonville, Florida, and Petersburg, Virginia. The highway connects most of the major cities of the East Coast—including Miami, Jacksonville, Richmond, Washington, D.C., Baltimore, Philadelphia, New York City, Boston and Portland, passing from the Southeastern United States to New England.
Transportation in the United States
With the development of the extensive Eisenhower "Interstate Highway System" in the 1950s, both long-distance trips and daily the commute were mostly by private automobile. This network was designed to exacting federal standards in order to receive federal funding. The system, , has a total length of , making it the world's second longest after China's, and the largest public works project in US history.
Yonge Street
Provincial downloading separated Yonge Street from Highway 11 during the 1990s. As a result, Highway 11 does not start until Crown Hill just outside Barrie, several kilometres north of where the name "Yonge Street" ends. The Guinness Book of World Records no longer lists Yonge Street as the longest street in the world and has not chosen a replacement street, but cites the Pan-American Highway as the world's longest "motorable road".
Thunderhill Raceway Park
Thunderhill Raceway Park is a motorsports complex located 7 miles West of Willows, California, United States, in the Sacramento Valley. It is the venue for the longest automobile race in the United States, the 25 Hours of Thunderhill, held annually during the first weekend in December.
Special routes of U.S. Route 95
The route now known as US 95 Spur was previously known as US 630 and US 30N. US 630 was an east–west United States highway. It was decommissioned in or around 1931. With a length of around , it was the shortest US route ever signed. It was concurrent with US 30N for its entire length. An earlier route numbered US-630 was proposed from Echo, Utah (northeast of Coalville) to Ogden, Utah, but was never signed in the field. U.S. Route 30N was a split route off of US-30 and was coterminous with US 630 at its west end in Oregon. East of Weiser, it was concurrent with what is now US-95 to Fruitland, Idaho, where it reconnected with US-30.
Alaska
Alaska has few road connections compared to the rest of the U.S. The state's road system covers a relatively small area of the state, linking the central population centers and the Alaska Highway, the principal route out of the state through Canada. The state capital, Juneau, is not accessible by road, only a car ferry, which has spurred several debates over the decades about moving the capital to a city on the road system, or building a road connection from Haines. The western part of Alaska has no road system connecting the communities with the rest of Alaska.
The Interstate Highways in Alaska consists of a total of 1082 miles. One unique feature of the Alaska Highway system is the Anton Anderson Memorial Tunnel, an active Alaska Railroad tunnel recently upgraded to provide a paved roadway link with the isolated community of Whittier on Prince William Sound to the Seward Highway about southeast of Anchorage at Portage. At , the tunnel was the longest road tunnel in North America until 2007. The tunnel is the longest combination road and rail tunnel in North America.
Vermont Route 100
Vermont Route 100 (VT 100) is a north–south state highway in Vermont in the United States. Running through the center of the state, it travels nearly the entire length of Vermont and is long. VT 100 is the state's longest state highway, the longest north-south route in Vermont, and the longest numbered highway in Vermont of any type.
U.S. Route 16 in South Dakota
US 16 is also known as Mount Rushmore Road in western South Dakota. The highway enters South Dakota east of Newcastle, Wyoming. It travels near Jewel Cave, the third-longest cave in the world. The highway goes through the city of Custer and shares alignment with US 385. East of Hill City, US 16 splits off US 385. It then becomes a four-lane divided highway, with the two roadways separated by up to in some places, including the old gold-mining town of Rockerville, South Dakota, which is contained entirely in the median of US 16. In Rapid City, US 16 follows Mount Rushmore Road to a concurrency with SD 44 (Omaha Street) to the southern terminus of I-190. US 16 stays concurrent with I-190 until both highways end at I-90.
U.S. Route 77 in Iowa
US 77 has never been a long route in Iowa. When it was extended into the state in 1929, it only traveled in Sioux City before crossing the Big Sioux River into South Dakota. After I-29 was built in Sioux City during the late 1950s, US 77 was moved onto the new Interstate Highway. At both historic ends of the highway in Iowa, bridge failures have caused US 77 to be detoured around Sioux City. In the mid-1980s, the national end of the highway was moved to the interchange with I-29.
This is not the shortest highway in the USA. Pretty certain the Old Edgerton Highway in Alaska is the shortest at less than 12 miles long.
List of state highways in Utah
The longest contiguous highway signed as a Utah State Route is State Route 24 at . However, State Route 30 is longer at when the unsigned concurrencies with I-84, I-15, and US-89 are included. The longest highway of any type in Utah is U.S. Route 89 at . The shortest state route is State Route 231, a connector route in Fairview, though this route is unsigned. The shortest signed route is State Route 103 at long, connecting Hill Air Force Base to I-15 and SR-126.
Geneva, Ohio
Three major routes pass through (or near) Geneva. Interstate 90, the northernmost east-west and coast-to-coast interstate, passes roughly two miles south of the city. There, a full-access interchange (exit 218) intersects Route 534, which passes through Geneva and terminates north of the city. Route 534 intersects Route 20, the longest road in the United States, in downtown Geneva.
Interstate 69
Interstate 69 (I-69) is an Interstate Highway in the United States currently consisting of seven disjointed parts with an original continuous segment from Indianapolis, Indiana, northeast to the Canada–US border in Port Huron, Michigan, at . The remaining separated parts are variously completed and posted or unposted parts of an extension southwest to the Mexican border in Texas. Of this extension—nicknamed the NAFTA Superhighway because it would help trade with Canada and Mexico spurred by the North American Free Trade Agreement—five pieces near Corpus Christi, Houston, northwestern Mississippi, Memphis, and Evansville have been newly built or upgraded and signposted as I-69. A sixth segment of I-69 through Kentucky utilizing that state's existing parkway system and a section of I-24 was established by federal legislation in 2008, but only a portion is signposted. A section of the previously existing Western Kentucky Parkway from Eddyville to Nortonville was approved and signposted in late 2011, with the Pennyrile Parkway between Nortonville and Henderson being signed as I-69 in 2015. This brings the total length to about .
Transportation in the United States
The Interstate system joined an existing National Highway System (a designation created for the legacy highway network in 1995), comprising 160,000 miles (256,000 kilometers) of roadway, a fraction of the total mileage of roads. The Interstate system serves nearly all major U.S. cities, often through the downtown areas (a point which triggered freeway and expressway revolts in the 1960s and 1970s). The distribution of virtually all goods and services involves Interstate highways at some point. Residents of American cities commonly use urban Interstates to travel to their places of work. The vast majority of long-distance travel, whether for vacation or business, is by the national road network; of these trips, about one-third (by the total number of miles driven in the country in 2003) utilize the Interstate system.
U.S. Route 50
U.S. Route 50 (US 50) is a major east–west route of the U.S. Highway system, stretching just over from West Sacramento, California, to Ocean City, Maryland, on the Atlantic Ocean. Until 1972, when it was replaced by Interstate Highways west of the Sacramento area, it extended (by way of Stockton, the Altamont Pass, and the Bay Bridge) to San Francisco, near the Pacific Ocean. The Interstates were constructed later and are mostly separate from this route. It generally serves a corridor south of Interstates 70 and 80 and north of Interstates 64 and 40. The route runs through mostly rural desert and mountains in the Western United States, with the section through Nevada known as "The Loneliest Road in America". In the Midwest, US 50 continues through mostly rural areas of farms as well as a few large cities including Kansas City, Missouri; St. Louis, Missouri; and Cincinnati, Ohio. The route continues into the Eastern United States, where it passes through the Appalachian Mountains in West Virginia before heading through Washington, D.C. From there, US 50 continues through Maryland as a high-speed road to Ocean City. Signs at each end give the length as , but the actual distance is slightly less, due to realignments since the former figure was measured. US 50 passes through a total of 12 states; California, Nevada, Utah, Colorado, Kansas, Missouri, Illinois, Indiana, Ohio, West Virginia, Virginia, and Maryland, as well as the District of Columbia.
Interstate 70 in Utah
Unlike most Interstate Highways, much of I-70 in Utah was not constructed parallel to or on top of an existing U.S. Highway. Portions of I-70 were constructed in areas where previously there were no paved roads. Because it was built over an entirely new route, I-70 has many features that are unique in the Interstate Highway System. For example, the between Green River and Salina makes up the longest distance anywhere in the Interstate Highway System with no motorist services. This same piece is noted as the longest highway in the United States built over a completely new route since the Alaska Highway, and the longest piece of Interstate Highway to open at a given time. The construction of the Utah portion of I-70 is listed as one of the engineering marvels of the Interstate Highway System.
U.S. Route 6
U.S. Route 6 (US 6), also called the Grand Army of the Republic Highway, honoring the American Civil War veterans association, is a main route of the U.S. Highway system. While it currently runs east-northeast from Bishop, California to Provincetown, Massachusetts, the route has been modified several times. The highway's longest-lasting routing, from 1936 to 1964, had its western terminus at Long Beach, California. During this time, US 6 was the longest highway in the country.
Arkansas Highway System
Another convention in 1907 formed road districts, but this did not help the situation either. Although the need for improvement was obvious, the citizens had trouble finding funding for their goals. In December 1913, Arkansas formed the "Dollarway", which was the name of a concrete road with asphalt concrete topping. It was opened near Pine Bluff. By 1914, a segment of was opened, the longest paved stretch in the United States. Today, the route is mostly covered by Highway 365, although some original concrete segments are still visible, and the Dollarway Road portion has been listed on the National Register of Historic Places.
California State Route 1
State Route 1 (SR 1) is a major north–south state highway that runs along most of the Pacific coastline of the U.S. state of California. At a total of just over , it is the longest state route in California. SR 1 has several portions designated as either Pacific Coast Highway (PCH), Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 (I-5) near Dana Point in Orange County and its northern terminus is at U.S. Route 101 (US 101) near Leggett in Mendocino County. SR 1 also at times runs concurrently with US 101, most notably through a stretch in Ventura and Santa Barbara counties, and across the Golden Gate Bridge.
Interstate 75
Interstate 75 (I-75) is a major north–south Interstate Highway in the Great Lakes and Southeastern regions of the United States. As with most Interstates that end in a five, it is a major cross-country, north–south route, one of the longest in the U.S., from southern Florida to the northern tip of Michigan. It travels from State Road 826 (SR 826, Palmetto Expressway) and SR 924 (Gratigny Parkway) on the Hialeah–Miami Lakes border (northwest of Miami, Florida) to Sault Ste. Marie, Michigan, at the Canadian border.
Interstate 10
Interstate 10 (I-10) is the southernmost cross-country Interstate Highway in the American Interstate Highway System. It stretches from the Pacific Ocean at California State Route 1 (Pacific Coast Highway) in Santa Monica, California, to I-95 in Jacksonville, Florida. Major cities connected by I-10 include (from west to east) Los Angeles, Phoenix, Tucson, El Paso, San Antonio, Houston, Baton Rouge, New Orleans, and Jacksonville. This freeway is part of the originally planned Interstate Highway network that was laid out in 1956, and its last section was completed in 1990. I-10 is the fourth-longest Interstate Highway in the United States, following I-90, I-80, and I-40. About one-third of its length is within the state of Texas, where the freeway spans the state at its widest breadth.
U.S. Route 206
U.S. Route 206 (US 206) is a north–south United States highway in New Jersey and Pennsylvania, United States. Only about a half a mile (800 m) of its length is in Pennsylvania; the Milford-Montague Toll Bridge carries it over the Delaware River into New Jersey, where it is the remainder of the route. The highway's northern terminus is near Milford, Pennsylvania at an intersection with US 209; some sources and signs show an overlap with US 209 to end at its parent route US 6. Its southern terminus is in Hammonton, New Jersey at an intersection with Route 54 and US 30. For much of its length, US 206 is a rural two-lane undivided road that passes through the Pine Barrens, agricultural areas, and the Appalachian Mountains of northwestern New Jersey, with some urban and suburban areas. The route connects several cities and towns, including Bordentown, Trenton, Princeton, Somerville, Netcong, and Newton. The road is known as the Disabled American Veterans Highway for much of its length.
U.S. Route 64 in North Carolina
U.S. Route 64 (US 64) is the longest numbered route in the U.S. state of North Carolina, running from the Tennessee state line to the Outer Banks. The route passes through the westernmost municipality in the state, Murphy, and one of the most easternmost municipalities, Manteo, making US 64 a symbolic representation of the phrase "from Murphy to Manteo" which is used to refer to the expanse of the state. The highway is a major east-west route through the central and eastern portion of the state.
U.S. Route 730
US 730 runs in Oregon and Washington and is listed as part of the National Highway System, a system of roads crucial to the nation's economy, defense and mobility, from its western terminus at I-84 east of Boardman to the end of its concurrency with US 395 in Umatilla. As a state highway in both states, the roadway is maintained by the Oregon Department of Transportation (ODOT) and Washington State Department of Transportation (WSDOT). US 730 has the highest designation of any United States Numbered Highway, or U.S. route, and is the shortest highway in the system. The highway is defined by the Washington State Legislature as SR 730, part of the Revised Code of Washington as §47.17.821.
Glenn Highway
The longest stretch of freeway in Alaska runs mostly along the Glenn Highway, beginning in north Anchorage, continuing onto the Parks Highway at the interchange of the two roads, and ending in the city limits of Wasilla, for a total of approximately 38 miles (61 km). This portion of the Glenn Highway is the only road access to Anchorage for most of the state (with the exception of the Kenai Peninsula on the Seward Highway), and as such is the main traffic corridor for Anchorage's suburbs in the Chugiak-Eagle River and Mat-Su areas. The highest point on the highway is at "Eureka Summit", which sits on the divide between the Chugach and Talkeetna mountain ranges.
Trans-Siberian Highway
The Trans-Siberian Highway is the unofficial name for a network of federal highways that span the width of Russia from the Baltic Sea of the Atlantic Ocean to the Sea of Japan. In the Asian Highway Network, the route is known as AH6. It stretches over from St. Petersburg to Vladivostok. The road disputes the title of the longest national highway in the world with Australia's Highway 1.
The highway became fully paved on 12 August 2015.
Interstate 90 in New York
Interstate 90 (I-90) is a part of the Interstate Highway System that runs from Seattle, Washington, to Boston, Massachusetts. In the U.S. state of New York, I-90 extends from the Pennsylvania state line at Ripley to the Massachusetts state line at Canaan, and is the second-longest highway in the state after NY 17. Although most of the route is part of the tolled New York State Thruway, two non-tolled sections exist along I-90 (the first, situated outside of Buffalo, is included in the Thruway system; the second, situated in the Capital District, is not part of the Thruway system and links Albany and its eastern suburbs). Within New York, I-90 has a complete set of auxiliary Interstates, which means that there are interstates numbered I-190 through I-990 in the state, with no gaps in between. For most of its length in New York, I-90 runs parallel to the former Erie Canal route, New York State Route 5 (NY 5), U.S. Route 20 (US 20) and the CSX railroad mainline that traverses the state.
Yonge Street
Yonge Street was formerly a part of Highway 11, which led to claims that Yonge Street was the longest street in the world. Running (mostly) concurrent with Yonge as far north as Barrie, then continuing beyond through central and northern Ontario to the Ontario-Minnesota border at Rainy River, the highway was over long. But Yonge Street could only be called the longest street in the world if were fully synonymous with Highway 11, which has never been the case.
U.S. Route 6 in Pennsylvania
U.S. Route 6 travels east–west near the north edge of the U.S. state of Pennsylvania from the Ohio state line near Pymatuning Reservoir east to the Mid-Delaware Bridge over the Delaware River into Port Jervis, New York. It is the longest highway segment in the Commonwealth. Most of it is a two-lane rural highway, with some freeway bypasses around larger towns. Except east of Dunmore, where it is paralleled by Interstate 84, it is the main route in its corridor. What is now Interstate 80—the Keystone Shortway—was once planned along the US 6 corridor as a western extension of I-84. The corridor was originally the Roosevelt Highway from Erie, Pennsylvania to Port Jervis, New York, designated Pennsylvania Route 7 in 1924. The PA 7 designation soon disappeared, but as US 6 was extended and relocated, the Roosevelt Highway followed it. The Pennsylvania section of US 6 was renamed the Grand Army of the Republic Highway in 1946; this name was applied to its full transcontinental length by 1953.
U.S. Route 45
In the state of Illinois, U.S. 45 runs from a bridge across the Ohio River from Paducah, Kentucky, through Shawnee National Forest and north to the Wisconsin border east of Antioch, Illinois. With a length of in Illinois, U.S. 45 is the longest numbered route in Illinois.
National Highway System (United States)
According to the Federal Highway Administration, the National Highway System includes roads important to the United States' economy, defense, and mobility, from one or more of the following road networks (specific routes may be part of more than one sub-system):The system includes 4% of the nation's roads, but carries more than 40% of all highway traffic, 75% of heavy truck traffic, and 90% of tourist traffic. All urban areas with a population of over 50,000 and about 90% of America's population live within of the network, which is the longest in the world.
Interstate 90 in Washington
Interstate 90 is the longest freeway in Washington state, at nearly in length, and is the only Interstate to traverse the state from west to east across the Cascade Mountains. It is listed as part of the National Highway System, classifying important to the national economy, defense, and mobility, and the state's Highway of Statewide Significance program, recognizing its connection to major communities. A section of I-90 between Seattle and Thorp named the Mountains to Sound Greenway was designated in 1998 as a National Scenic Byway, in recognition of its scenic views.
Panamericana (film)
Panamericana is a 2010 documentary about the life at the longest road on Earth: a road-trip from Mexico to Argentina through 12 countries and for 13,000 kilometers.
Alberta Highway 40
Two interesting facts about highway 40 are: The segment from roughly Hinton to Grande Prairie is part of the shortest fully paved land route from the USA to the Klondike Gold fields in the Yukon, and if the segments of the Forestry Trunk Road and Highway 40 were connected, the total length would be approximately and it would be the second longest highway in Alberta.
U.S. Route 45 in Illinois
In the U.S. state of Illinois, U.S. Route 45 is a major north–south highway that runs from the Brookport Bridge over the Ohio River at Brookport north through rural sections of eastern Illinois and then through the suburbs of Chicago to the Wisconsin border east of Antioch. This is a distance of . U.S. 45 is the longest numbered route in Illinois.
Interstate 81 in Virginia
Interstate 81 (I-81) is an highway. In the U.S. state of Virginia, I-81 runs for , making the portion in Virginia longer than any other state's portion. It is also the longest Interstate highway within the borders of Virginia. It stretches from the Tennessee state line near Bristol to the West Virginia state line near Winchester.
Massachusetts Route 28
The original form of Route 28 was as a New England interstate route established in 1922 to run from Buzzards Bay to New Hampshire. The route itself was overlaid on several early turnpike roads constructed in the early 19th century. Except for an extension into Cape Cod in 1926, the overall highway layout and routing is largely unchanged from its original design. Route 28 has been realigned in several places when newer, higher quality roads were built. At a length of nearly , Route 28 is the longest state-numbered highway in Massachusetts, and the second-longest highway, behind U.S. Route 20.
List of Interstate Highways in New York
There are a combined of Interstate Highways within New York, which handles about 19 percent of vehicle travel in New York. At approximately , I-78 is the shortest main Interstate Highway, while I-90 is the longest, spanning within New York. I-878, located in Queens, is the shortest active route in the Interstate Highway System at .
List of U.S. Highways in Michigan
In Michigan, the US Highway System covers about of mainline highways and another of special routes. There are 13 mainline highways and 30 special routes in total, including one business route that is unsigned. Two of the mainline highways in the Upper Peninsula exit the state and re-enter, resulting in two discontinuous segments of highway for each in Michigan. The longest US Highway in the state is US Highway 23 (US 23) at just over spanning from the Ohio state line north to the Straits of Mackinac in the Lower Peninsula, while the shortest is the segment of US 8 south of Norway in Dickinson County. Special routes range in length from about for Business US 2 (Bus. US 2) in Ironwood to for Bus. US 131 in Kalamazoo.
Interstate 240 (Oklahoma)
Interstate 240 (I-240) is an Interstate Highway in Oklahoma, United States, that runs 16.22 miles (26.1 km) west from Interstate 40 to Interstate 44 in southern Oklahoma City.

The interstate overlaps SH-3, the longest Oklahoma state highway, for its entire length.
Interstate 90
Interstate 90 (I-90) is an east–west transcontinental freeway, and the longest Interstate Highway in the United States at . Its western terminus is in Seattle, at State Route 519 near T-Mobile Park and CenturyLink Field, and its eastern terminus is in Boston, at Route 1A near Logan International Airport.
Texas state highway system
Texas state highways are a network of highways owned and maintained by the U.S. state of Texas. The Texas Department of Transportation (TxDOT) is the state agency responsible for the day-to-day operations and maintenance of the system. Texas has the largest state highway system, followed closely by North Carolina's state highway system. In addition to the nationally numbered Interstate Highways and U.S. Highways, the highway system consists of a main network of state highways, loops, spurs, and beltways that provide local access to the other highways. The system also includes a large network of farm to market roads that connect rural areas of the state with urban areas and the rest of the state highway system. The state also owns and maintains some park and recreational roads located near and within state and national parks, as well as recreational areas. All state highways, regardless of classification, are paved roads. The Old San Antonio Road, also known as the El Camino Real, is the oldest highway in the United States, first being blazed in 1691. The length of the highways varies from US 83's inside the state borders to Spur 200 at just long.
United States Numbered Highway System
In general, U.S. Routes do not have a minimum design standard, unlike the later Interstate Highways, and are not usually built to freeway standards. Some stretches of U.S. Routes do meet those standards. Many are designated using the main streets of the cities and towns through which they run. New additions to the system, however, must "substantially meet the current AASHTO design standards". As of 1989, the United States Numbered Highways system has a total length of .
Virginia State Route 40
State Route 40 (SR 40) is a primary state highway in the southern part of the U.S. state of Virginia. It runs from State Route 8 at Woolwine east to State Route 10 at Spring Grove, about half the width of Virginia. It is the longest state-numbered (not U.S. or Interstate) route in Virginia.
Interstate 10 in Texas
Interstate 10 (I-10) is the major east–west Interstate Highway in the Southern United States. In the U.S. state of Texas, it runs east from Anthony, at the border with New Mexico, through El Paso, San Antonio and Houston to the border with Louisiana in Orange, Texas. At just under , the Texas segment of I-10, maintained by the Texas Department of Transportation, is the longest continuous untolled freeway in North America that is operated by a single authority. It is also the longest stretch of highway with a single designation within a single state. Mile marker 880 and its corresponding exit number in Orange, Texas, are the highest numbered mile marker and exit on any freeway in North America. After widening was completed in 2008, a portion of the highway west of Houston is now also believed to be the widest in the world, at 26 lanes. There is a wider section in China on the G4 Beijing–Hong Kong–Macau Expressway; however, that section is a toll plaza approach.
Massachusetts Turnpike
The Massachusetts Turnpike (colloquially "Mass Pike" or "the Pike") is a toll road in the U.S. state of Massachusetts that is maintained by the Massachusetts Department of Transportation (MassDOT). The turnpike begins at the New York state line in West Stockbridge, linking with the Berkshire Connector portion of the New York State Thruway. Spanning along an east–west axis, it is entirely concurrent with the portion of Interstate 90 (I-90) that lies within the state. The turnpike is the longest Interstate Highway in Massachusetts, while I-90 in full (which begins nationally in Seattle, Washington) is the longest Interstate Highway in the United States.
U.S. Route 13 in North Carolina
The section of U.S. Route 13 (US 13) in North Carolina is the longest, home to of its length. It runs southwest to northeast through eastern North Carolina, beginning at Interstate 95. Most of the routing is rural, serving only three cities of considerable size along the entire route; the rest passes through forests and farmland. US 13 is usually only two lanes wide unless it is co-signed with other highways, usually near cities as bypasses.
Interstate 91
Interstate 91 (I-91) is an Interstate Highway in the New England region of the United States. It provides the primary north–south thoroughfare in the western part of the region. The Interstate's southern end is in New Haven, Connecticut, at Interstate 95 and its northern end is at Derby Line, Vermont, a village in the town of Derby at the Canadian border, where it continues past the Derby Line-Rock Island Border Crossing as Autoroute 55. I-91 is the longest of three Interstate highways whose entire route is located within the New England states (the other two highways being I-89 and I-93) and is also the only primary (two-digit) Interstate Highway in New England to intersect all five of the others that run through the region. The largest cities along its route are New Haven, Connecticut, Hartford, Connecticut, Springfield, Massachusetts, Brattleboro, Vermont, White River Junction, Vermont, and St. Johnsbury, Vermont in order from south to north.

Philadelphia and Lancaster Turnpike
The Philadelphia and Lancaster Turnpike, first used in 1795, is the first long-distance paved road built in the United States, according to engineered plans and specifications. It links Lancaster, Pennsylvania, and Philadelphia at 34th Street, stretching for sixty-two miles. However, the western terminus was actually at the Susquehanna River in Columbia. The route is designated Pennsylvania Route 462 from the western terminus to US 30, where that route takes over for the majority of the route. The US 30 designation ends at Girard Avenue in the Parkside neighborhood of Philadelphia, where State Route 3012 takes it from there to Belmont Avenue. At Belmont Avenue, State Route 3005 gets the designation from Belmont Avenue until the terminus at 34th Street.
Lincoln Highway (Omaha)
The Lincoln Highway in Omaha, Nebraska, runs east–west from near North 183rd Street and West Dodge Road in Omaha, Nebraska, towards North 192nd Street outside of Elkhorn. This section of the Lincoln Highway, one of only that were paved with brick in Nebraska, is one of the most well-preserved in the country. The roadway was listed on the National Register of Historic Places in 1984. The Lincoln Highway was the first road across the United States, traversing coast-to-coast from Times Square in New York City to Lincoln Park in San Francisco, California.
Route of the Lincoln Highway
Traveling westward from the Douglas Street Bridge. West to 18th or 24th Street depending on year. South to Farnam Street. West to 40th where it turned North to Dodge Street, Dodge to 78th and North to Cass/West Dodge Road. The Lincoln Highway in Omaha went by several landmarks, including The Blackstone Hotel, John Sutters Mill (1847) with the oldest billboard on The Lincoln Highway (1913-1930), Highway 30 (1930-1969 until the Douglas Street/AK-SAR-BEN Bridge was torn down) and Highway 6 (which meets in Council Bluffs and says good-bye at Saddle Creek and Dodge to go under The Saddle Creek Bridge South to Center Street), The Tower Gas Station and campgrounds at 78th and Dodge and Peony Park at 78th and Cass St./West Dodge Road. The longest stretch of original Lincoln Highway brick roadway in the country is in Omaha from approx. 174th to approx 203rd.The best way to access is at 180th and Dodge St. and travel North. Leaving the city it took city streets through Waterloo where it joined U.S. Route 275 to Fremont. From Fremont, it continued west on U.S. Route 30 through Central City, Grand Island, Wood River, Kearney, Lexington, Cozad, Gothenburg, North Platte, Sutherland, Ogallala, Chappell, Sidney, and Kimball to the Wyoming state line.

Oklahoma State Highway 3
State Highway 3, also abbreviated as SH-3 or OK-3, is a highway maintained by the U.S. state of Oklahoma. Traveling diagonally through Oklahoma, from the Panhandle to the far southeastern corner of the state, SH-3 is the longest state highway in the Oklahoma road system, at a total length of via SH-3E (see below).
Plainfield, Illinois
Certain older parts of Plainfield have suffered from extreme traffic congestion. Before Interstate 55 was built just east of the town in the late 1950s, U.S. Route 30, The Lincoln Highway and U.S. Route 66 (sometimes referred to as "The Mother Road") merged into one street for three blocks on what is now Illinois Route 59. This merge is now only shared by U.S. 30 and Lincoln Highway, between Plainfield/Joliet Road on the south to Lockport Street on the north, but continues to be an area of heavy traffic congestion even outside heavy commuting periods. At one time, the two longest paved highways in the world (Lincoln Highway and U.S. Route 66) crossed within Plainfield. The highways only crossed each other twice and both locations are in Will County. The other location is in neighboring Joliet.
List of Interstate Highways in Nebraska
The Interstate Highways in Nebraska are the segments of the national Interstate Highway System that are owned and maintained by the U.S. state of Nebraska, totaling . The longest of these, by far, is Interstate 80 (I-80) at a length just over . After the system was created in 1956, the state department of roads began construction on its Interstates immediately and upon completion of I-80 in 1964 was the first state to complete its mainline Interstate. With the completion of Interstate 129 in 1977, Nebraska completed its contribution to the Interstate Highway System.
Texas State Highway 99
State Highway 99, also known as the Grand Parkway, is a highway in Texas, United States that opened its first section in 1994. When State Highway 99 is complete, it will be the longest beltway in the U.S., and the third (outer) loop within Houston–The Woodlands–Sugar Land metropolitan area, with Interstate 610 being the first (inner) loop, and Beltway 8 (Sam Houston Tollway) being the second (middle) loop. The proposed loop has been divided into 11 separate segments for construction and funding purposes.
North Carolina Highway 20
The original NC 20 was at one time the longest numbered route in North Carolina, running from the Tennessee border to the port city of Wilmington, a distance of . After the introduction of U.S. highways in North Carolina in 1934, the route was carved up between routes US 19, US 70, US 74, US 76, and US 17.
U.S. Route 40 in Maryland
U.S. Route 40 (US 40) in the U.S. state of Maryland runs from western Maryland to Cecil County in the state's northeastern corner. With a total length of over , it is the longest numbered highway in Maryland. Almost half of the road overlaps or parallels with Interstate 68 or Interstate 70, while the old alignment is generally known as U.S. Route 40 Alternate, U.S. Route 40 Scenic, or Maryland Route 144. West of Baltimore, in the Piedmont and 
Appalachian Mountains / Blue Ridge region of the Western Maryland panhandle of the small state, the portions where it does not overlap an Interstate highway are mostly two-lane roads. The portion northeast of Baltimore going to Wilmington, in northern Delaware and Philadelphia in southeastern Pennsylvania before crossing the Susquehanna River at the north end of the Chesapeake Bay, is a four-lane divided highway, known as the Pulaski Highway (named for American Revolutionary War (1775-1783) foreign military volunteer of Polish cavalry officer Casimir Pulaski, 1745-1779).
Oregon Route 140
Oregon Route 140 is an Oregon state highway that serves the southern portion of the state. It is the longest state highway in Oregon, running 237 miles from the community of White City, Oregon (just north of Medford), through Klamath Falls and on to Lakeview. It then continues east, eventually descending into the state of Nevada.
U.S. Route 66
U.S. Route 66 (US 66 or Route 66), also known as the Will Rogers Highway, the Main Street of America or the Mother Road, was one of the original highways in the U.S. Highway System. US 66 was established on November 11, 1926, with road signs erected the following year. The highway, which became one of the most famous roads in the United States, originally ran from Chicago, Illinois, through Missouri, Kansas, Oklahoma, Texas, New Mexico, and Arizona before ending in Santa Monica, California, near Los Angeles, covering a total of . It was recognized in popular culture by both the hit song "(Get Your Kicks on) Route 66" and the "Route 66" television show in the 1960s. In John Steinbeck's classic-American novel, "The Grapes of Wrath" (1939), the road, "Highway 66", was turned into a powerful symbol of escape and loss.
Taconic State Parkway
The Taconic State Parkway (often called the Taconic or the TSP and known administratively as New York State Route 987G or NY 987G) is a divided highway between Kensico Dam and Chatham, the longest parkway in the U.S. state of New York. It follows a generally northward route midway between the Hudson River and the Connecticut and Massachusetts state lines, along the Taconic Mountains. Its southernmost are a surface road; from the junction with the Sprain Brook Parkway northward it is a limited-access highway. It has grade-separated interchanges from that point to its northern terminus; in the three northern counties, there are also at-grade intersections, many with closed medians, allowing only right-in/right-out turns. It is open only to passenger vehicles, as with other parkways in New York, and maintained by the state Department of Transportation (NYSDOT), the fourth agency to have that responsibility.
U.S. Route 6 in Ohio
U.S. Route 6 (US 6) is a part of the United States Numbered Highway System that runs from Bishop, California to Provincetown, Massachusetts. US 6 is the second longest federal highway in the United States, second only to U.S. Route 20. In Ohio, the road runs west-east from the Indiana state line near Edgerton to the Pennsylvania state line near Andover. The that lie in Ohio are maintained by the Ohio Department of Transportation (ODOT). US 6 serves the major cities of Sandusky, Lorain, and Cleveland. The highway is also called the Grand Army of the Republic Highway to honor the Union forces of the American Civil War. The alternate name was designated in 1953.
Iowa Highway 3
Iowa Highway 3 is a state highway that runs from east to west across the state of Iowa. Highway 3 is the longest state highway in Iowa, at long. Iowa 3 begins at the South Dakota state line where it continues as South Dakota Highway 50 and ends at an interchange with U.S. Route 61 / U.S. Route 151. It is designated the American Veterans Memorial Highway for its entirety. It is located approximately halfway between Interstate 80 and Interstate 90.
Seekonk Speedway
The track holds the distinction of being the longest continually family operated race track in the United States, under the guidance of the Venditti family since it opened on May 30, 1946. The track is sanctioned by NASCAR under the Whelen All-American Series. It is also the widest track in New England at 72 feet. The track's all-time winningest drivers include George Summers and "Radical" Rick Martin of Westport, Massachusetts. Typically starting on the first Sunday of May, Seekonk Speedway is host to short track action every Saturday night, depending on the weather. On Friday nights, Seekonk Speedway is open for lower-budget competition, open to drivers of varying skills. The track has seating all around the track, allowing patrons to see the whole track from any seat. Optional pit passes are available for sale which allow patrons to enter the paddock area to meet the drivers and see the cars.
Pacific Highway (United States)
Good roads advocate and road-building pioneer Sam Hill was perhaps the main motivating force behind building the original Pacific Highway as a "national auto trail"; from Blaine, Washington, on the Canada–US border, where he would build his Peace Arch, through Oregon to the Siskiyou Mountains of northwestern California. The road was built in the early 20th century—long before the U.S. Highway System was established. In 1923, its of pavement made it the longest continuous stretch of paved road in the world at the time. The Pacific Highway later extended north to Vancouver, British Columbia, and south through San Francisco to San Diego in Southern California.
Interstate 57
In the state of Illinois, Interstate 57 runs from the bridge over the Mississippi River north to Chicago. I-57 is the longest Interstate Highway in Illinois. Its route follows essentially the earlier route of US 51 in southernmost Illinois (US 51 has been diverted to I-57 where I-57 has always been close to old US 51 between Future City and Dongola) before taking a northeastward diagonal to Illinois 37, which remains intact as a town-to-town through route, past its interchange with Interstate 24 (the northwestern terminus of Interstate 24) near Pulleys Mill and a short duplex with Interstate 64 near Mount Vernon north to Effingham, where it has a short concurrence with Interstate 70. It then follows US 45 bypassing cities of Champaign and Urbana (where it meets Interstates 72 and 74), and heads north to Onarga whereafter it follows the formerly duplex path of US 45 and (now decommissioned in most of Illinois) old US 54 to Kankakee. At Kankakee it heads northward largely parallel to the now decommissioned route of old US 54 (since renumbered largely as Illinois 50) into the Chicago area, meeting Interstate 80 in Hazel Crest, Interstate 294 in Blue Island, and feeding Interstate 94 on Chicago's South Side.
U.S. Route 99 in California
By 1968, US 99 was completely decommissioned with the completion of I-5 in Washington and California, but the highway's phasing out actually began July 1, 1964, thanks to the passage of Collier Senate Bill No. 64 on September 20, 1963. The bill launched a major program designed to greatly simplify California's increasingly complicated highway numbering system and eliminate concurrent postings like the aforementioned US 60/US 70/US 99. The highways that replaced it are:The stretch between Wheeler Ridge and Red Bluff is signed as SR 99 which makes it California's second-longest state highway behind SR 1. However, the newly enacted "Historic U.S. Route 99" extends from Indio starting from I-10 in the Coachella Valley all the way down the Imperial Valley to Calexico on the Mexican border with Mexicali, Baja California, Mexico.U.S. Route 99W was a short-lived alternate of US 99 in the Central Valley of California, running from north of Manteca via French Camp to Stockton. At the same time, from roughly 1929 to 1933, U.S. Route 99E ran to the east, having the same termini as US 99W.
U.S. Route 9 in New York
US 9 spawns more letter-suffixed state highways than any other route in New York, including the longest, New York State Route 9N (NY 9N). Outside of the cities it passes through, it is a mostly a two-lane road, save for two expressway segments in the mid-Hudson region. For much of its southern half it follows the Hudson River closely; in the north it tracks I-87 (the Adirondack Northway).
List of U.S. Highways in Alabama
The U.S. Highways in Alabama are the subset of the United States numbered highway system. These highways in the U.S. state of Alabama are maintained by the Alabama Department of Transportation (ALDOT). There are 19 U.S. highways that travels through Alabama, totaling . U.S. Route 31 (US 31) is the highway with the longest segment in Alabama, with . The shortest is US 72 Alternate, crossing of North Alabama. One former U.S. highway existed in Alabama: US 241.
