On December 21, 1935, a section from Garden City to Midland was added, creating a gap. On February 11, 1937, the western section extended westward to Gardendale, replacing SH 216. On August 1, 1938, the section from Garden City to Sterling City was restored, partially closing the gap. On November 19, 1938, SH 158 extended west to 7.5 miles northeast of Ector-Winkler County line, its current end. On July 9, 1945, FM 652 was designated from SH 158 to SH 302.

On August 19, 1948, SH 158 was extended southeast to Ballinger, replacing SH 109. On September 26, 1963, SH 158 was extended along old location US 83. The two disconnected portions were finally connected on May 6, 1969 when Farm to Market Road 387, completed in 1959, was re-designated as SH 158.
Business routes
SH 158 has one business route. Business State Highway 158-B is a business loop that runs on the former routing of SH 158 through Midland.
