 The highway traveled from Texarkana on the eastern border to El Paso on the western border, via Dallas and Fort Worth, Abilene, and Midland–Odessa.

 In 1920, the entire length of the highway was designated as part of the Bankhead Highway, a transcontinental Auto trail.
 In the Texas Department of Transportation's 1939 state highway renumbering, most of SH 1 was redesignated as U.S. Route 80, as well as U.S. Route 287, Texas State Highway 16, and others.
 Most of these highways were replaced by Interstate 10, Interstate 20, and Interstate 30.
 The only portion of SH 1 that existed after 1939 was a short spur located in Dallas.
 Texas State Highway 1 was officially cancelled on August 20, 1952.
 Due to the highway's historic value, a highway can not be designated as Texas State Highway 1 unless by the order of TxDOT Executive Director or by the Transportation Commission.
