U.S. Route 80 or U.S. Highway 80 (US 80) is a major east-west United States Numbered Highway in the Southern United States, much of which was once part of the early auto trail known as the Dixie Overland Highway. As the "0" in the route number indicates, it was originally a cross-country route, from the Pacific Ocean to the Atlantic Ocean. Its original western terminus was at Historic US 101 in San Diego, California. However, the entire segment west of Dallas, Texas, has been decommissioned in favor of various Interstate Highways and state highways. Currently, the highway's western terminus is at an interchange with Interstate 30 (I-30) on the Dallas–Mesquite, Texas city line. Its eastern terminus is in Tybee Island, Georgia near the Atlantic Ocean. Between Jonesville, Texas and Kewanee, Mississippi, US 80 runs parallel to or concurrently with Interstate 20. It also currently runs through Dallas, Texas; Shreveport, Louisiana; Jackson, Mississippi; Montgomery, Alabama; Columbus, Georgia; Macon, Georgia; and Savannah, Georgia.
U.S. Route 290 is an east–west U.S. Highway located entirely within the state of Texas. Its western terminus is at Interstate 10 southeast of Segovia, and its eastern terminus is at Interstate 610 in northwest Houston. It is the main highway between Houston and Austin and is a cutoff for travelers wanting to bypass San Antonio on Interstate 10. Throughout its length west of Austin, US 290 cuts across mountainous hills comprising the Texas Hill Country and the Edwards Plateau; between Austin and Houston, the highway then travels through gradually hilly grasslands and pine forests comprising the Gulf Coastal Plains.

A total of seven special routes of U.S. Route 90 exist.
There are fourteen business routes of Interstate 35 (I-35): nine are in Texas, two are in Iowa, and three are in Minnesota.
Interstate business routes are roads connecting a central or commercial district of a city or town with an Interstate bypass. These roads typically follow along local streets often along a former US route or state highway that had been replaced by an Interstate. Interstate business route reassurance markers are signed as either loops or spurs using a green shield shaped and numbered like the shield of the parent Interstate highway.
Numerous special routes of U.S. Route 67, all business routes, exist. One other route, formerly an alternate route in western Illinois, has since been downgraded to state Route 267.
All of the business loops within Texas are maintained by the Texas Department of Transportation (TxDOT). Interstate 20 (I-20) has fifteen business loops in the state, all located in western Texas. Along I-20, TxDOT identifies each business route as Business Interstate 20 followed by an alphabetic suffix. Along Texas Interstates, the alphabetic suffixes on business route names ascend eastward and northward. There are gaps in the alphabetic values to allow for future system expansion. The alphabetic naming suffixes are included as small letters on the bottom of route shields.
Alternate U.S. Highway 77 is a north–south auxiliary route of US 77, located entirely within the state of Texas. The route was commissioned in 1953, when US 77 was rerouted in southeast Texas.
Farm to Market Road 1053 (FM 1053) is a Farm to Market Road in the U.S. state of Texas maintained by the Texas Department of Transportation (TxDOT). The road, located in Pecos, Crane, and Ector counties, begins along the concurrent routes of Business Interstate 10-G, U.S. Route 285 (US 285), and U.S. Route 385 (US 385) in the city of Fort Stockton and continues to the north ending at Interstate 20 (I-20) near Penwell. The road passes through the towns of Imperial, where it intersects FM 11, and Tubbs Corner, where it crosses State Highway 329 (SH 329). The road also has major intersections with I-10 / US 67 in Fort Stockton as well as FM 1450 and FM 1233.
There are currently four business routes of U.S. Route 175 that are designated and maintained by the Texas Department of Transportation (TxDOT). The business routes in the US state of Texas are traditionally short spurs or loops that connect the main route, in this case, U.S. Route 175 (US 175), to the center or commercial district of a city. The routes commonly follow the course of an decommissioned state highway, or the old course of the main route. Business routes are signed with the traditional US 175 highway shield, and with a small "business plate" placed above the marker. TxDOT regards business routes as official highways, and is responsible for the maintenance of the route.
