History

Loop 20 was designated on September 26, 1939 from US 96 (later US 59, and now SH 359) to US 83 in Laredo as a renumbering of SH 12 Loop. On September 27, 1985, Loop 20 extended from SH 359 to US 59. On August 29, 1996, it extended north to FM 3464 2 miles east of I-35. On May 28, 1998, Loop 20 extended west and southwest to the Mexico border, concurrent with part of FM 3464. On May 29, 2008, Loop 20 was to be rerouted south of SH 359 to US 83, with the old route (the original portion) to become Texas State Highway Spur 260. The section from SH 359 to Mangana-Hein Road (7 miles (11 km)) opened in 2011, and as a result, the old route was officially signed as Spur 260. On August 29, 2013, a shortcut opened south of SH 359, with the old route becoming Texas State Highway Spur 259.

Texas State Highway 12 highway in Texas

State Highway 12 (SH 12) is an east–west state highway that runs from I-10 in Vidor to Deweyville on the Texas-Louisiana boundary in east Texas. The route was designated on August 27, 1959 as a renumbering of SH 235 to smooth the travel transition with Louisiana Highway 12, with which it connects.

Texas State Highway Spur 260 highway in Texas

Texas Spur 260, also known as Jaime Zapata Memorial Highway, is a state highway in southeastern Laredo, Texas connecting U.S. Route 83 and Texas State Highway 359. The route was designated in 2008 but continued to be signed as part of Texas State Highway 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.

Future expansion

The Texas Department of Transportation's Laredo District is preparing for future growth with plans to upgrade Loop 20 into a freeway by building overpasses at major intersections and constructing frontage roads. [2] A short freeway section, which is co-signed with both Interstate 69W and U.S. Highway 59, currently exists from the World Trade International Bridge east to Interstate 35 and TxDOT recently constructed a diamond interchange at Loop 20's intersection with U.S. Highway 59 in eastern Laredo; [3] the stack interchange with Interstate 35, locally known as the Milo Interchange, is partially complete. As of 2008, TxDOT planned to complete interchanges and overpasses at all of Loop 20's major intersections within the next ten years. [4]

Texas Department of Transportation governmental agency in Texas

The Texas Department of Transportation is a government agency in the U.S. state of Texas. Though the public face of the agency is generally associated with the construction and maintenance of the state's immense state highway system, the agency is also responsible for overseeing aviation, rail, and public transportation systems in the state.

Diamond interchange common type of road junction

A diamond interchange is a common type of road junction, used where a freeway crosses a minor road.

Stack interchange

A stack interchange, or colloquially butterfly junction, is a particular, free-flowing type of design for interchanges, meaning grade-separated road junctions. It is referred to as a directional interchange in the American Association of State Highway and Transportation Officials Policy on Geometric Design of Highways and Streets.

As of 2011, TxDOT is currently constructing an interchange at State Highway 359. An additional interchange at Clark Boulevard, Texas State Highway Spur 400, has been announced by the City of Laredo. [5]

Texas State Highway Spur 400 highway in Texas

Spur 400 is the state highway designation for the eastern portion of Clark Boulevard, from Arkansas Blvd to Loop 20, in Laredo, Texas. Spur 400 is a four-lane roadway, and is 1.174 miles (1.889 km) long.

The Cuatro Vientos Road portion of the route is designed for future expansion to a freeway throughout, as well as an extension to the south to U.S. 83 in the vicinity of Rio Bravo, possibly connecting to a future international bridge.

Previous routes

The northwest section of Loop 20 west of I-35 to Farm to Market Road 1472 was originally part of Farm to Market Road 3464 , [6] [7] a 1.15-mile (1.9 km) road designated on October 26, 1983 to connect I-35 to FM 1472 in northern Laredo, Texas. On April 1, 1988, the route was extended east 2.0 miles (3.2 km) over FM 3488, which was cancelled. [8] On June 27, 1995, FM 3464 became Urban Road 3464. On June 29, 2000, FM 3464 was cancelled, as the section west of I-35 was removed from the state highway system, and the section east of I-35 was already part of Loop 20.

Interstate 37 Interstate in South Texas

Interstate 37 (I-37) is a 143.0-mile (230.1 km) Interstate Highway located within the southern portion of the U.S. state of Texas. The highway was first designated in 1959 as a route between Corpus Christi and San Antonio. Construction in the urban areas of Corpus Christi and San Antonio began in the 1960s and the segments of the Interstate Highway in rural areas were completed by the 1980s. Prior to I-37, the route between Corpus Christi and San Antonio was served by a combination of State Highway 9 from Corpus Christi to Three Rivers and U.S. Route 281 (US 281) from Three Rivers to San Antonio. As a result of the construction of I-37, SH 9 was removed from the State Highway System.

U.S. Route 181 highway in the United States

U.S. Highway 181 is a south–north U.S. Highway located entirely in the state of Texas. Both termini are at Interstate 37, the road that it mainly parallels to the east. US 181 begins in Corpus Christi, Texas at mile marker 0 to the south, through south-central Texas to just south of San Antonio to the north, for a total length of 137 miles (220 km).

U.S. Highway 175 (US 175) is an east-west United States highway completely within the state of Texas. It comes very close to meeting its "parent" route, US 75, but decommissioning and rerouting in downtown Dallas, Texas brings it a couple of miles short. Before the decommissioning of US 75 south of downtown Dallas in favor of Interstate 45, US 175 met its "parent" US 75. US 175's western terminus is in Dallas, Texas at Interstate 45. The highway's eastern terminus is in Jacksonville, Texas at an intersection with US 69.

U.S. Route 290 highway in Texas

U.S. Route 290 is an east–west U.S. Highway located entirely within the state of Texas. Its current western terminus is at Interstate 10 near Harper, and its eastern terminus is at Interstate 610 on the northwest side of Houston.

Texas State Highway Loop 1 highway in Texas

Loop 1 is a freeway which provides access to the west side of Austin in the U.S. state of Texas. It is named Mopac Expressway after the Missouri Pacific Railroad. Local residents will invariably use the name "MoPac" rather than calling the road by its number which can cause much confusion as few signs along the road use this name. Adding to the confusion, the road goes in a mostly straight line rather than a loop.

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.

Loop 1604, also known as the Charles W. Anderson Loop, is a highway loop that encircles San Antonio, Texas, spanning approximately 95.6 miles (153.9 km). What began as a two-lane highway has been upgraded to a four-lane freeway along its northern stretches. The Texas Department of Transportation (TxDOT) is planning to add new lanes between SH 151 and I-10 east as toll lanes. An environmental impact statement study is currently underway to determine other improvements. Loop 1604 is named for former Bexar County Judge Charles W. Anderson, who died from cancer in 1964 after serving for 25 years on the bench.

Spur 482, known better as Storey Lane, is a short connector route located in the Dallas area. The route originates at the site of the former Texas Stadium and ends northwest of Love Field.

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 an 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.
