Texas State Highway 82

SH 82 was originally designated on August 21, 1923 on a route from the West Texas town of Monahans south to Ft. Stockton, with a planned extension south to Sanderson, replacing part of SH 17.[3] On October 16, 1928, SH 82 was extended north to Kermit.[4] On June 25, 1929, SH 82 was extended north to the New Mexico border.[5] The planned extension to Sanderson was transferred to newly designated U.S. Highway 285 (cosigned since 1935) on September 26, 1939. On February 27, 1958, the remainder of the route was renumbered as SH 18, to coordinate with its intersection with New Mexico State Road 18.

On January 29, 1975, SH 82 was designated over its current route in Jefferson County from SH 87 to Louisiana Highway 82. On January 7, 1987, the route was extended 2.1 miles (3.4 km) to SH 73 incorporating the former Spur 214. The section west of Sabine Pass was previously proposed on September 19, 1956 as SH 362 (for access to the proposed levee; to be cancelled when construction was completed), but the designation was changed to FM 1900 on December 13, 1956 (still was to be cancelled when construction was completed), and FM 1900 was completed, and FM 1900 was cancelled on October 30, 1958 due to completion of construction.
