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.
State Highway 7 (SH 7) is an east–west state highway in the U.S. state of Texas that runs from Interstate 35 at Eddy to U.S. Highway 84 about 3 miles (4.8 km) west of the Louisiana state line. Between Crockett and Nacogdoches, SH 7 passes through the Davy Crockett National Forest. Commissioned on April 4, 1917, SH 7 is one of the original state highways established in Texas, and has been re-routed several times since its original conception. In earlier years, SH 7 mostly followed present day U.S. Highway 84, U.S. Highway 67, U.S. Highway 70 among other highways between northwest Texas and the Louisiana state line. By 1939, most of the mileage belonging to SH 7 was transferred to the U.S. Highway System, leaving the highway extant only within eastern Texas. SH 7 subsequently went through several other major reroutings, truncations and extensions between 1939 and 1990, before becoming the highway it is today.
State Highway 46 is a 71.4-mile (114.9 km) state highway in the U.S. state of Texas that runs from SH 16 east of Bandera to the intersection of SH 123 and SH 123 Business just south of Seguin.
State Highway 31 runs from U.S. 84 northeast of Waco via Corsicana, Athens, Tyler, Kilgore to U.S. 80 in Longview.
Loop 1604 is the outer highway loop encircling San Antonio, Texas, spanning approximately 95.6 miles (153.9 km). Originally constructed as a two-lane highway, the northern segment of the route, from US 90 in western San Antonio to Kitty Hawk Road in northeastern Bexar County, has been upgraded to a four-lane freeway. Loop 1604 is designated the Charles W. Anderson Loop in honor of former Bexar County Judge Charles W. Anderson, who died from cancer in 1964 after serving for 25 years.
State Highway 359 is a state highway that runs from Skidmore in southeastern Texas, near Corpus Christi, southwest and west to Laredo at the international border with Mexico.
State Highway 316 is a Texas state highway that runs from near Port Lavaca southeast to the ghost town of Indianola. This route was designated on April 1, 1939.
State Highway 322 is a Texas state highway that runs from US 259 in Henderson to I-20/US 259/Loop 281 in Longview.
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.
A total of twelve special routes of U.S. Route 79 exist, divided between the states of Arkansas, Louisiana, Tennessee and Texas. Currently, they are all business routes, except for one bypass of Humboldt, Tennessee, and one bypass of Homer, Louisiana.
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 U.S. 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.
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 a 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.
