At Spearfish Canyon Highway, Alt US 14 leaves the overlap with BL 90 and turns south. A spur of the Spearfish Recreational Trail leave Alt.

The route meets US 85 again in Deadwood. The routes run together through Deadwood before splitting again, and Alt. US 14 turns east along Boulder Canyon Highway.
