The Interstate Highways in Texas are all owned and maintained by the U.S. state of Texas. [2] The Texas Department of Transportation (TxDOT) is the agency responsible for the day-to-day maintenance and operations of the Interstate Highways in Texas. The Interstate Highway System in Texas covers 3,239.7 miles (5,213.8 km) and consists of twelve primary routes, seven auxiliary routes and Interstate 35 (I-35) which is split into two branches, I-35E and I-35W, that provide access to both Fort Worth and Dallas. The longest segment of Interstate Highway in Texas is I-10 at 878.6 miles (1,414.0 km); the shortest is I-110 at 0.9 miles (1.4 km).
The construction of the Interstate Highway System in Texas began well before these routes were designated as Interstate Highways. A 50-mile (80 km) stretch of I-45 between Galveston and Houston was opened in 1951, eight years before it was designated I-45. It was also the first urban expressway in Texas. In 1962, 43 miles (69 km) of I-35 opened in Bexar County, the first section of Interstate Highway to open from county line to county line in a large metropolitan area. [3] Portions of I-10 west of San Antonio took much longer to complete due to the vast open spaces and lack of nearby labor. The majority of the construction of this section of I-10 occurred in the 1970s and 1980s and was complete by the early 1990s. The section east of San Antonio was completed 20 years earlier in 1972. [4] The opening of a 6-mile (10 km) section of I-27 in 1992 completed the Interstate Highway System in Texas. [5]
Planning is ongoing for a proposed extension of I-69 southward from its original terminus in Indiana through Texas to the United States–Mexico border. [6] If complete as planned, I-69 will extend about 650 miles (1,050 km) across Texas, from the Louisiana state line in the Texarkana–Shreveport area to South Texas. [7] The first 6.2-mile (10.0 km) portion was approved in 2011, with signage posted December 6, 2011.

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 35 is a 206.5-mile (332.3 km) state highway near the southeastern edge of Texas, United States, that is maintained by the Texas Department of Transportation (TxDOT). It runs primarily south–north, paralleling the Gulf of Mexico for much of its length, from a junction with Interstate 37 in Corpus Christi to Interstate 45 in southeastern Houston.
State Highway 64 is a Texas state highway that runs from Wills Point via Tyler to Henderson.
State Highway 70 is a state highway in Texas. The route runs approximately 315 miles (507 km) from US 277 near Blackwell to US 83 south of Perryton.
State Highway 72 is a Texas state highway that runs approximately 111 miles (179 km) from near Fowlerton to Cuero in South Texas.
State Highway 142 is a short Texas state highway that runs from San Marcos to Lockhart.
State Highway 144 (SH 144) is a 39.027-mile (62.808 km) state highway in Bosque, Somervell, and Hood counties in Texas, United States, that runs from Meridian to Granbury.
State Highway 186 is a state highway in the Rio Grande Valley in Hidalgo and Willacy counties in Texas, United States, that connects U.S. Route 281 (US 281), future Interstate 69C, and Farm to Market Road 1017 (FM 1017) in Linn with the Gulf of Mexico at Port Mansfield.
Farm to Market Road 1171 is a farm to market road in Denton County, Texas.
Farm to Market Road 400 is a farm to market road located in Lynn, Lubbock, Hale, and Swisher counties in the Llano Estacado of Texas.
U.S. Route 281 (US 281) is a United States Numbered Highway that runs from the Mexican border in the Rio Grande Valley to the Canadian border near Dunseith, North Dakota. In the state of Texas, the highway is a major south–north corridor, connecting Brownsville to the Oklahoma state line at the Red River in Burkburnett. Several segments of U.S. 281 are concurrent with Interstate routes, including I-69C in the Rio Grande Valley, I-37 in San Antonio, and I-44 north of Wichita Falls.
The following special routes exist or existed parallel to U.S. Route 87 (US 87) in Texas, primarily along former alignments. They are varyingly designated by the Texas Department of Transportation (TxDOT) as business routes of US 87, state highway loops and spurs, and business loops of Interstate 27 (I-27).
A total of ten special routes of U.S. Route 90 exist.
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 sign and numbered like the shield of the parent Interstate highway.
