Another SH 107 was designated from Santa Anna to the McCulloch county line on July 13, 1925.[4]

On February 14, 1927, the SH 107 from Aspermont to Newcastle was renumbered as SH 120. As a result, there was only one SH 107 from Santa Anna to the McCulloch County line. On April 13, 1927, SH 107 extended south to Brady. On September 9, 1927, SH 107 was canceled as the route became an extension of SH 4.[5]

On August 6, 1929, SH 4 was rerouted west, and SH 107 returned on the route from Santa Anna to Brady. On January 19, 1932, SH 107 was canceled, as the route became an extension of SH 16. On May 28, 1932, a new SH 107 was designated from Combes to Edinburg.[6]

On July 15, 1935, SH 107 was canceled.[7]

On December 21, 1935, SH 107 was restored.[8]

It was extended west then south through Mission to Hidalgo on September 26, 1939, absorbing SH 250 and part of SH 48.[9]

The route has changed little since then, with the stretch from Mission to Hidalgo being transferred to FM 1016 on November 23, 1948. On July 29, 1974, SH 107 was extended south one block over FM 1016 to Conway & 7th Streets. On May 21, 1979, SH 107 was extended from old US 77 to new US 77 and from old US 83 to new US 83.
