Glen Canyon Dam Bridge

The concrete and steel structure spans 1271 feet across the Colorado River, with its deck positioned 700 feet above the water level.

The United States Bureau of Reclamation constructed this bridge in 1959 to facilitate the transportation of materials for the Glen Canyon Dam project.

The bridge represents a significant engineering achievement in American Southwest infrastructure development, connecting Arizona and Utah across the Colorado River.

Located on US Route 89, this bridge provides essential passage for vehicles traveling between southern Arizona and northern Utah through the Colorado Plateau.

At the time of its completion, this steel structure held the record as the highest arch bridge in the world, containing 3,920 tons of structural steel.
