State Highway 82 (SH 82) is a state highway in the U.S. state of Texas that runs 13 miles (21 km) from the Louisiana border as a continuation of Louisiana Highway 82 to the East Texas city of Port Arthur. A roadway existed from at least 1970, when the Gulfgate Bridge (later renamed Martin Luther King Bridge) was completed; the route was designated SH 82 in 1975. The designation had previously applied to a route in West Texas, from 1923 to 1958.
