Iron Mountain Road - Black Hills, SD

This winding road runs between Mount Rushmore National Memorial and the junction of US 16A and SD 36. Constructed in 1933, only a portion of this road lies within the park, but it is a must-see.

Along the highway, visitors will find wildfire exhibits, pigtail bridges, magnificent Black Hills scenery and tunnels that frame Mount Rushmore.

Winding drives throughout the park are enjoyed at a slower pace. When making plans, please allow ample time to travel at a safe speed – generally 25 miles-per-hour or slower. Expect travel time of about 45 to 60 minutes.
