Oklahoma State Highway 20

State Highway 20 (abbreviated SH-20) is a highway in northeastern Oklahoma. Its eastern terminus is at the corner of Oklahoma, Arkansas, and Missouri near Southwest City, Missouri; its western terminus is at State Highway 18 near Ralston. The highway runs a total length of 142.7 miles (229.7 km). It has no lettered spur routes.

Route description

SH-20 begins just north of the Arkansas River at SH-18 near Ralston. From there, it heads east through Osage County for 20 miles (32 km) without crossing any other highway. At mile 20.4, it meets State Highway 99 in Hominy. East of Hominy, SH-20 crosses Lake Skiatook before passing through Skiatook and entering Tulsa County. Shortly after entering Tulsa County, SH-20 has a junction with SH-11. Four miles later, it has an interchange with US-75. After running through Collinsville, it turns southward onto the US-169 freeway.

SH-20 splits from US-169 north of Owasso. It then enters Claremore, where it meets SH-88 and SH-66 (old Route 66). It connects to the Claremore toll plaza on I-44/Will Rogers Turnpike. East of Claremore, SH-20 becomes a divided expressway before intersecting US-69 in Pryor. West of Salina, the highway bridges Lake Hudson. In Salina, SH-20 meets SH-82, with which it begins a concurrency.

Texas State Highway 20

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, US 62, US 85, and US 180.

Until the late 1930s, the route designation belonged to a highway in central Texas along the route of present day US 290. The current route predates the Texas highway system having been a portion of several historic auto trails. The route was included at the creation of the state system as part of SH 1. With the establishment of the U.S. numbered highway system, the route became US 80 and the SH 1 designation was eventually dropped. SH 20 was designated over the route when US 80 was relocated over I-10 before it too was decommissioned in western Texas.
