State Highway Spur 421 (Spur 421) is a state highway spur in the San Antonio, Texas, USA metropolitan area. [1]
Spur 421 begins at an intersection with I-10 north of Downtown San Antonio. The route follows Culebra Road to the west before turning to the northwest along Bandera Road. The designation ends at Loop 410 and SH 16; southbound SH 16 follows the Loop 410 freeway, while northbound SH 16 continues along Bandera Road. [1] [2]
Spur 421 is a former route of SH 16, and was designated (along with Spur 422) on November 16, 1965, after SH 16 was rerouted around the west side of San Antonio along the Loop 410 freeway. [1] The section of Spur 421 south of Callaghan Road was proposed for decommissioning in 2014 (Spur 421 would have also replaced the section of SH 16 north to Eckhert Road as well) as part of TxDOT's San Antonio turnback proposal, which would have turned back over 129 miles of roads to the city of San Antonio, but the city of San Antonio rejected that proposal. [3]
The entire route is in Bexar County.

Interstate 37 (I-37) is a 143-mile (230 km) Interstate Highway located within the southern portion of the US 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 (SH 9) from Corpus Christi to Three Rivers and US Highway 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. 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. 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.
Interstate 410 (I-410), colloquially Loop 410, is an auxiliary route of I-10 around San Antonio, Texas. It is identified as the Connally Loop in honor of former Texas Governor John Connally.
State Highway 16 is a south–north state highway in the U.S. state of Texas that runs from Zapata on the boundary with Mexico to U.S. Highway 281 24 miles (39 km) south of Wichita Falls. It is the longest state highway in Texas at almost 542 miles (872 km), but is only the ninth-longest of any highway classification in the state.
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 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.
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.
