State highway loops in Texas are owned and maintained by the Texas Department of Transportation (TxDOT).
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 6 (SH 6) runs from the Red River, the Texas–Oklahoma state line, to northwest of Galveston, where it is known as the Old Galveston Highway. In Sugar Land and Missouri City, it is known as Alvin-Sugarland Road and runs perpendicular to Interstate 69/U.S. Highway 59 (I-69/US 59). In the Houston area, it runs north to Farm to Market Road 1960 (FM 1960), then northwest along US 290 to Hempstead, and south to Westheimer Road and Addicks, and is known as Addicks Satsuma Road. In the Bryan–College Station area, it is known as the Earl Rudder Freeway. In Hearne, it is known as Market Street. In Calvert, it is known as Main Street. For most of its length, SH 6 is not a limited-access road. In 1997, the Texas Legislature designated SH 6 as the Texas Korean War Veterans Memorial Highway.
State Highway 123 is a north–south state highway in Texas, United States, that connects U.S Route 181 in Karnes City with Interstate 35 (I-35) in San Marcos. The route was initially proposed in 1927 and has had minimal changes to its routing since then.
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.
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 37 is a state highway that runs from the Oklahoma state line near Albion to Mineola in the northeast corner of the state.
In the US state of Texas, Interstate 40 (I-40) runs west–east through the panhandle in the northwest part of the state. The only large city it passes through is Amarillo, where it meets the north end of I-27. The entire section of I-40 in Texas is designated as a Purple Heart Trail route.
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.
U.S. Highway 59 (US 59) in the U.S. state of Texas is named the Lloyd Bentsen Highway, after Lloyd Bentsen, former U.S. senator from Texas. In northern Houston, US 59, co-signed with Interstate 69 (I-69), is the Eastex Freeway. To the south, which is also co-signed with I-69, it is the Southwest Freeway. The stretch of the Southwest Freeway just west of The Loop was formerly one of the busiest freeways in North America, with a peak AADT of 371,000 in 1998.
State Highway Spur 260 (Spur 260), also known as Jaime Zapata Memorial Highway, is a state highway in southeastern Laredo, Texas, United States, that connect U.S. Route 83 (US 83) with Texas State Highway 359 (SH 359) and northbound Texas State Highway Loop 20 (Loop 20). The route was designated in 2008 but continued to be signed as part of Loop 20 until the opening of Cuatro Vientos Road in July 2011, when the Loop 20 designation was shifted to the new route. The contemporary Spur 260 constitutes the original extent of Loop 20, as originally designated in 1939.
All of the business loops within Texas are maintained by the Texas Department of Transportation (TxDOT). Interstate 20 (I-20) has 15 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.
All of the business loops are maintained by the Texas Department of Transportation (TxDOT). Interstate 45 (I-45) has four business loops in the state, all located in northern Texas. Along I-45, TxDOT identifies each business route as Business Interstate 45 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.
There are currently three business routes of U.S. Route 83 in Texas 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 83 (US 83), 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 83 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.
