State Highway 1 was a state highway in the U.S. state of Texas. 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. SH 1 was approximately 842 miles (1,355 km) long, and was one of the original 25 Texas state highways, which were designated on June 21, 1917. 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 67, 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 September 26, 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.

Vandalism to the road signage as a result of its numbering had reached epidemic proportion by 1989, driving a resolution that the number of the road needed to be changed. The cost of resigning the roadway was considered reasonable by local governments, compared to that of the measures by law enforcement agencies that would be necessary to stop the vandalism. In 1992, the district requested and was granted renumbering of this route to State Highway 112.
