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.
