Texas State Highway 30

Historic SH 30

SH 30 was a route proposed on October 8, 1917 to run from Wichita Falls to Abilene.[2] On August 19, 1918, it extended to Paint Rock.[3] On April 23, 1919, it extended to Sabinal.[4] On August 21, 1923, the southern portion was rerouted into Del Rio on August 21, 1923 over part of SH 7A and SH 4.[5] The old route became part of rerouted SH 23, with the section south of Menard cancelled. That same day, SH 30 extended to the Oklahoma border, replacing a portion of SH 2. On March 17, 1924, SH 30 extended to the Mexico border.[6] On September 26, 1939, the highway was cancelled as U.S. Highway 277 was routed over its entirety from Del Rio to Wichita Falls.

The current iteration of SH 30 was designated on December 15, 1960, replacing SH 45 and parts of FM 60 and FM 158 to avoid confusion with I-45. On May 21, 1979, SH 30 was extended from I-45 to SH 19, replacing part of SH 19, which was rerouted over former Loop 405.
