U.S. Highway 14A is an alternate route for U.S. Highway 14 between Spearfish and Sturgis 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 (BL 90), which is used as a frontage road along the south side of I-90. In between the Alt. US 14 and I-90 is the Spearfish Recreational Trail. BL 90/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 BL 90 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 the 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 U.S. Truck Route 85, 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 Highway 14A ends in Sturgis at the I-90/US 14 interchange at Exit 30, but the road continues as another Business Loop of I-90 with an overlap of SD 34 and 79.
