State Highway 188 (SH 188) is a state highway in the Coastal Bend region of Texas. It runs 41.327miles from Mathis east to Aransas Bay between Rockport and Port Aransas. SH 188 was established in its current form in 1992, after a previous incarnation existed from 1932 to 1942.
SH 188 was previously designated on November 30, 1932, as a connector route between then-SH 5 and Roxton.[1] This route was canceled on April 29, 1942, and was replaced by FM 38.
SH 188 was designated on December 22, 1992, replacing part of FM 881 and part of FM 1069, of which SH 188 was concurrent with. On June 29, 1993, SH 188 was extended 1.8miles over another part of FM 1069, canceling the section of FM 1069 east of the junction with SH 188, transferring it to SH 188, and the remainder of FM 881 was redesignated as part of FM 1069.
