Texas state highways are a network of highways owned and maintained by the U.S. state of Texas. The Texas Department of Transportation (TxDOT) is the state agency responsible for the day-to-day operations and maintenance of the system. Texas has the largest state highway system, followed closely by North Carolina's state highway system. In addition to the nationally numbered Interstate Highways and U.S. Highways, the highway system consists of a main network of state highways, loops, spurs, and beltways that provide local access to the other highways. The system also includes a large network of farm to market roads that connect rural areas of the state with urban areas and the rest of the state highway system. The state also owns and maintains some park and recreational roads located near and within state and national parks, as well as recreational areas. All state highways, regardless of classification, are paved roads. The Old San Antonio Road, also known as the El Camino Real, is the oldest highway in the United States, first being blazed in 1691. The length of the highways varies from US 83's 893.4 miles (1,437.8 km) inside the state borders to Spur 200 at just 0.05 miles long.
State Highway 44 (SH 44) is a Texas state highway that runs from west of Encinal to Corpus Christi, Texas. This highway is also known as the Cesar Chavez Memorial Highway outside the city limits of Robstown, Banquete, Agua Dulce, Alice, and Corpus Christi in Nueces and Jim Hogg counties.
State Highway 255 is a Texas state highway that allows international traffic to bypass Laredo. Located in Webb County, the highway provides a connection between the Colombia Solidarity International Bridge to Interstate 35 at exit #24. The route opened in 2000 as the Camino Colombia Toll Road, and was one of the few operating toll roads in the United States to have gone through the legal process of foreclosure. The toll designation was removed from the route in 2017.
Loop 20, also known as the Bob Bullock Loop and Cuatro Vientos Road, is a highway loop that runs to the north and east of the city of Laredo, Texas. Loop 20 extends from the World Trade International Bridge at its northern point to Mangana-Hein Road at its southern point. The current route varies in construction from a 2-lane road to a freeway with frontage roads.
Farm to Market Road 1472 (FM 1472) is a farm-to-market road in the U.S. state of Texas that connects the industrial area of Laredo to the Laredo–Colombia Solidarity International Bridge, and then runs roughly parallel to the Rio Grande into rural Webb County. In the urban sections of Laredo, it is a six-lane route known locally as Mines Road.
There are fourteen business routes of Interstate 35 (I-35): nine are in Texas, two are in Iowa, and three are in Minnesota.
