Iron Mountain Road

Pigtail bridges and tunnels that frame Mount Rushmore.

Part of the Peter Norbeck Scenic Byway, US 16A twists through the forest on corkscrew "pigtail" bridges and through narrow tunnels engineered to frame Mount Rushmore in the distance.

Pair it with Needles Highway and the Wildlife Loop for a classic Black Hills scenic-drive day.

Highlights

  • Pigtail bridges
  • Tunnels framing Mount Rushmore
  • Forest overlooks

Local tips

  • Speeds are slow and curves are tight. Large RVs and trailers should check restrictions first.
  • Build the day around daylight: this is a drive to enjoy, not hurry.
