Iron Mountain Road & Pigtail Bridges

Known for its “pigtail” bridges, Iron Mountain Road redefined what a road could be. Climbing 17 miles from Custer State Park to the entrance of Mount Rushmore, you’ll wind over stacked loops of wooden bridges and through one-lane tunnels that perfectly frame Mount Rushmore. Such care was taken not to disturb the landscape that some sections of the road actually divide into one-lane one-way ribbons that swoop and bound through mixed pine and deciduous forest.
