Hayden Arch Bridge Access provides parking and river access to the Shoshone River below the Buffalo Bill Dam, featuring a pull-off area near the historic 1925 arch bridge.

The location offers access to a fast-flowing protected pool area surrounded by dramatic canyon walls, making it a popular spot for fishing and hiking; however, there is no designated parking, so users should pull off the road carefully without blocking the nearby power plant gate.

This scenic access point is part of the Old Yellowstone Road, which also serves pedestrians and cyclists exploring the historic route through Shoshone Canyon.
