The United States Numbered Highway System is an integrated network of roads and highways numbered within a nationwide grid in the contiguous United States. As the designation and numbering of these highways were coordinated among the states, they are sometimes called Federal Highways, but the roadways were built and have always been maintained by state or local governments since their initial designation in 1926.
U.S. Route 10 or U.S. Highway 10 (US 10) is an east–west United States Numbered Highway located in the Midwest and Great Lakes regions of the U.S. Despite the "0" as the last digit in the number, US 10 is no longer a cross-country highway, and it never was a full coast-to-coast route. US 10 was one of the original long-haul highways, running from Detroit, Michigan, to Seattle, Washington, but then lost much of its length when new Interstate Highways were built on top of its right-of-way.
U.S. Highway 57 (US 57) is a 98-mile (158 km) north–south intrastate United States highway that follows a nearly east–west route in the southwestern part of the U.S. state of Texas. The highway's northern (eastern) terminus is about 50 miles (80 km) south of San Antonio, Texas, between Devine and Pearsall, at an intersection with Interstate 35. Its southern (western) terminus is in Eagle Pass, at the Rio Grande, where it continues into Piedras Negras, Coahuila, as Mexican Federal Highway 57.
Interstate 515 (I-515) was a 20.54-mile-long (33.06 km) spur route of I-15 in the US state of Nevada that ran from the junction of I-15, US 93 and US 95 in Downtown approximately 20 miles (32 km) southeast to just north of Railroad Pass in southeastern Henderson. The freeway connected traffic headed from Boulder City and Henderson to Downtown Las Vegas via a direct, high-speed route, and it ran concurrently with, US 93, and US 95 along its entire length.
U.S. Route 97 (US 97) is a major north–south route of the United States Numbered Highway System in the Pacific Northwest region. It runs for approximately 670 miles (1,078 km) through the states of California, Oregon, and Washington, primarily serving interior areas on the east side of the Cascade Mountains. The highway terminates to the south at a junction with Interstate 5 (I-5) in Weed, California, and to the north at the Canadian border near Osoyoos, British Columbia, where it becomes British Columbia Highway 97. Major cities on the US 97 corridor include Klamath Falls, Bend, and Redmond in Oregon; and Yakima, Ellensburg, and Wenatchee in Washington. A portion of the highway in California and Oregon is part of the Volcanic Legacy Scenic Byway.
U.S. Route 163 is a 64-mile (103 km) U.S. Highway that runs from US 160 northward to US 191 in the U.S. states of Arizona and Utah. The southernmost 44 miles (71 km) of its length are within the Navajo Nation. The highway forms part of the Trail of the Ancients, a National Scenic Byway. The highway cuts through the heart of Monument Valley and has been featured in numerous movies and commercials.
Interstate 275 (I-275) is an Interstate Highway in Tennessee that serves Knoxville by connecting the downtown with I-75/I-640/US Route 25W (US 25W). Measuring 2.98 miles (4.80 km) in length, it runs from a northern terminus at the junction with I-75/I-640/US 25W to a southern terminus at I-40. I-275 was formerly a section of I-75, which was rerouted onto I-640 in 1980 after a section of that route was completed.
Interstate 155 (I-155) is a north–south spur of I-55 that provides an Interstate connection for the Illinois cities of Peoria and Lincoln. The northern terminus is just east of Peoria, at I-74 exit 101 in Morton. The southern terminus, which is northwest of Lincoln, is located on I-55 at exit 127. The highway is 32.13 miles (51.71 km) long.
U.S. Bicycle Route 1 is a cross-country bicycle route that will run the length of the United States eastern seaboard from Florida to Maine. It is one of the two original U.S. Bicycle Routes, the other being U.S. Bicycle Route 76.
The United States Bicycle Route System is the national cycling route network of the United States. It consists of interstate long-distance cycling routes that use multiple types of bicycling infrastructure, including off-road paths, bicycle lanes, and low-traffic roads. As with the complementary United States Numbered Highways system for motorists, each U.S. Bicycle Route is maintained by state and local governments. The USBRS is intended to eventually traverse the entire country, like the Dutch National Cycle Routes and the United Kingdom's National Cycle Network, yet at a scale similar to the EuroVelo network that spans Europe.
State Route 198 is a highway completely within Utah County in northern Utah that connects Santaquin to Spanish Fork via Payson and Salem. The route runs 16 miles (26 km). The entire length of the route is an old routing of US-6 and US-50; a portion of the route was also US-91. These routes were re-aligned or truncated after the Interstate Highway System was constructed through this part of Utah.
In the U.S. state of Nevada, U.S. Route 93 Alternate is an alternate route of U.S. Route 93 located in the northeast part of the state. It connects Lages Station to Wells via the town of West Wendover.
U.S. Highway 63 (US 63) is a part of the United States Numbered Highway System that spans 1,286 miles (2,070 km) from Ruston, Louisiana to a point southwest of Ashland, Wisconsin. Within the state of Louisiana, the highway travels 35.40 miles (56.97 km) from the national southern terminus at the junction of Interstate 20 (I-20), US 167, and Louisiana Highway 146 (LA 146) in Ruston to the Arkansas state line at Junction City.
Several special routes of U.S. Route 95 exist. In order from south to north they are as follows.
Several special routes of U.S. Route 19 (US 19) exist. In order from south to north, they are as follows.
U.S. Bicycle Route 95 (USBR 95) is a U.S. Numbered Bicycle Route in California, Washington, and Alaska along the West Coast in the United States, that is also planned to run through Oregon. It has three designated sections in California, Washington, and Alaska. The first section, running from Valdez to Delta Junction in Alaska, was designated in May 2011.
Interstate 87 (I-87) is a partially completed Interstate Highway in the US state of North Carolina, the shortest designated primary Interstate Highway at 12.90 miles (20.76 km) long. The completed portion is in eastern Wake County, between Raleigh and Wendell; the majority of the completed route is known as the Knightdale Bypass, while the remaining three miles (4.8 km) follows the Raleigh Beltline (I-440). It is planned to continue northeast through Rocky Mount, Williamston, and Elizabeth City, ending in Norfolk, Virginia. It is signed as north–south, in keeping with the sign convention for most odd-numbered interstates, but the route goes primarily east–west, with the eastern direction aligning to the north designation. The entire route is concurrent with US Highway 64 (US 64), with portions also concurrent with I-440 and US 264.
U.S. Bicycle Route 50 (USBR 50) is a planned east–west cross country U.S. Bicycle Route that currently consists of two discontiguous sections: a western section between San Francisco and Border, Utah, and an eastern section between Terre Haute, Indiana, and Washington, D.C.
