Iron Mountain Road
pigtail bridges that frame Mount Rushmore
Iron Mountain Road is one of the places Roamward flags on the Needles Highway because it gives the drive its texture: pigtail bridges that frame Mount Rushmore. Use it as a planned pull-over instead of letting the route become a blur between towns.
How it fits the drive
The Needles Highway runs Custer State Park, SD (SD-87). Granite spires and one-lane tunnels in the Black Hills.
