U.S. Route 79 (US 79) is a United States highway in the Southern United States. The route is officially considered and signed as a north–south highway, but its path is actually more of a diagonal northeast–southwest highway. The highway's northern/eastern terminus is in Russellville, Kentucky, at a junction with U.S. 68. Its southern/western terminus is in Round Rock, Texas, at an interchange with Interstate 35, ten miles (16 km) north of Austin. US 79, US 68, and Interstate 24/US 62 are the primary east–west access points for the Land Between the Lakes recreation area straddling the Kentucky/Tennessee border.
