South Dakota Highway 79 (SD 79) is a 241.115-mile (388.037 km) state highway in western South Dakota, United States, that runs along the western tier of the state from the Nebraska state line in the south to the North Dakota state line in the north.
Route description
SD 79's southern terminus is at the Nebraska state line south of Oelrichs. The route runs concurrently with U.S. Route 385 (US 385) and then with US 18 for a total of 30 miles (48 km) before splitting onto its own roadway at Maverick Junction, just southeast of Hot Springs. SD 79 runs east of the Black Hills to Rapid City, where it joins US Route 16 Truck Bypass around the east side of Rapid City up to Interstate 90. The road continues north and runs concurrently with US 14 and Interstate 90 westbound toward Sturgis. Leaving Sturgis, SD 79 leads to Bear Butte State Park and briefly runs concurrently with U.S. Route 212 south of Newell. Near North Dakota, the highway passes through the South Dakota portion of Custer National Forest. SD 79 then joins SD 20 for a short concurrent run, and finally turns northward until it reaches North Dakota, where its roadway continues north as North Dakota Highway 22.
