State Highway 7 (SH 7) is an east–west state highway in the U.S. state of Texas that runs from Interstate 35 at Eddy to U.S. Highway 84 about 3 miles (4.8 km) west of the Louisiana state line. Between Crockett and Nacogdoches, SH 7 passes through the Davy Crockett National Forest. Commissioned on April 4, 1917, SH 7 is one of the original state highways established in Texas, and has been re-routed several times since its original conception. In earlier years, SH 7 mostly followed present day U.S. Highway 84, U.S. Highway 67, U.S. Highway 70 among other highways between northwest Texas and the Louisiana state line. By 1939, most of the mileage belonging to SH 7 was transferred to the U.S. Highway System, leaving the highway extant only within eastern Texas. SH 7 subsequently went through several other major reroutings, truncations and extensions between 1939 and 1990, before becoming the highway it is today.
