Texas State Highway 355

Below is a list and summary of some of the deleted state highways (i.e., those with no current routing) as outlined by the Texas Department of Transportation designation files, indicated by having zero current mileage.

State Highway 1 ran from El Paso through Dallas to Texarkana. It was the first highway designated in 1917. In 1926, the United States Highway System was designated, with US 80 colocated from El Paso to Dallas and US 67 from Dallas to Texarkana. In 1939, the dual designations were removed, leaving TX 1 only on a small stretch west of Dallas. This section was redesignated as State Loop 260 in 1952. Since that time, the number "may only be assigned by the Executive Director of the Texas Department of Transportation or the Transportation Commission."

State Highway 2 was originally designated in 1917, running from Wichita Falls southeast to Fort Worth. The route then split in two at Waco, with one branch travelling southwest through Austin and San Antonio before ending at Laredo, while the eastern branch travelled southeast through Houston, ending at Galveston. The western route was assigned the US 81 routing in 1926, the northern portion of the eastern routing was transferred to TX 6, and the southern portion was transferred to US 75. The co-designation with US 81 was dropped completely in 1939.

State Highway 13 was originally designated in 1917, running through the Texas Panhandle along the Ozark Trail. It generally referenced the routing due west from Amarillo to the New Mexico state line. In 1926, US Route 66 was co-located along the route. The co-designation was dropped completely in 1939.
