("TX 20" redirects here. TX 20 may also refer to Texas's 20th congressional district.) State Highway 20 or SH 20 is a 78.1-mile (125.7 km) highway maintained by the Texas Department of Transportation (TxDOT) that runs from New Mexico State Road 460 at the state line between Texas and New Mexico at Anthony in El Paso County to Interstate 10 at McNary in Hudspeth County. The route passes through the city of El Paso as well as suburban and rural farming communities along the Rio Grande. With the exception of a stretch north of central El Paso where the route crosses north of I-10, the route generally runs in a narrow belt between I-10 and the Rio Grande. The route has connections to every international border crossing with Mexico in the El Paso area and has important intersections with US 54,
