State Highway 7 (SH 7) is an east–west state highway that runs from Interstate 35 at Eddy to U.S. Highway 84 about west of the Texas-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 border. 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. Route description Including concurrencies with other state highways, Texas State Highway 7 (SH 7) reaches a total length of between Interstate 35 (I-35) and Farm to Market Road 107 (FM 107) at Bruceville-Eddy and a junction with U.S. Highway 84 (US 84) near the Louisiana state line. The highway travels through mostly flat, rural landscape, that lies between the Dallas-Fort Worth area and Houston. The highway also passes several small rivers, retaining dams and man made reservoirs, as well as cutting through the Davy Crockett National Forest and passing the northern boundary of the Sabine National Forest. SH 7 currently serves nine counties and nine incorporated towns and cities. Bruceville-Eddy to Nacogdoches SH 7 begins at an interchange with I-35 and FM 107 at Bruceville-Eddy in McLennan County. The highway proceeds due east crossing the Falls County line less than a mile east of the I-35 interchange. About east of I-35, SH 7 intersects with the southern terminus of FM 2643. Just outside of Chilton, SH 7 meets US 77 and Business SH 7-B at an interchange. Where the highway continues straight ahead as the business route, SH 7 proper becomes concurrent with US 77, passing the eastern terminus of FM 1950, then splitting off on its own again, continuing east where US 77 continues south towards Victoria. SH 7 meets up with the eastern terminus of Bus. SH 7-B in Chilton as well as the southern terminus of FM 434. The highway heads east, passing the eastern terminus of FM 935 and SH 320 near
