Route description

The South Dakota section of US 14 enters the state from Wyoming concurrent with Interstate 90. It passes through Spearfish, Sturgis, Rapid City, and Wall, before leaving I-90. US 14 then passes through Philip, Midland, Pierre, Highmore, Miller, Wolsey, Huron, De Smet, Arlington, and Brookings, then leaving the state at the Minnesota state line.[1]

US 14A winds through the northern part of the scenic Black Hills taking travelers from Sturgis to Spearfish.

The Laura Ingalls Wilder Historic Highway incorporates US 14 from De Smet in the west to Rochester, Minnesota, in the east.

US 14 and US 83 serve Pierre, one of only four state capitals not on the Interstate Highway System.

The South Dakota section of US 14 is legally defined at South Dakota Codified Laws § 31-4-134.[2]

U.S. Highway 14A (US 14A) is an alternate route for US 14 between Spearfish and Sturgis, South Dakota, located mostly south of the I-90/US 14 overlap. The route begins at the I-90/US 14/US 85 overlap at exit 14 which serves 27th Street. It briefly runs south and then turns west along East Colorado Boulevard (I-90 Bus.), which is used as a frontage road along the south side of I-90. In between US 14A and I-90 is the Spearfish Recreational Trail. I-90 Bus./US 14A moves away from I-90 just before the intersection with Sandstone Hills Drive. At Spearfish Canyon Highway, US 14A leaves the overlap with I-90 Bus. and turns south. A spur of the Spearfish Recreational Trail leave US 14A at Winterville Road, and, in the vicinity of the southern trailhead of the Spearfish Path, the route begins to wind around Spearfish Creek and Spearfish Canyon running through the North Hills of Black Hills National Forest, which includes scenic areas for both cars and hikers, and unincorporated communities and ghost towns such as Maurice, Victoria, and Elmore.

In Cheyenne Crossing, the road turns left and begins the first of two overlaps with US 85. The two routes form a concurrency from there to Lead, then are separated where it continues north also overlapping US 85 Truck, only to turn east as the routes run through Center City and Backtail. The route meets US 85 again in Deadwood. The routes run together through Deadwood before splitting again, and US 14A turns east along Boulder Canyon Highway. US 14A ends in Sturgis at the I-90/US 14 interchange at exit 30, but the road continues as another I-90 Bus. with an overlap of South Dakota Highway 34 (SD 34) and SD 79.
