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.
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.
