Glen Canyon National Recreation Area

Glen Canyon Dam Bridge. Glen Canyon Dam bridge is behind Glen Canyon Dam. When it was built in 1959, It was the highest arch bridge of its kind at a height of 700 feet. For construction, two cable way towers were built on the canyon rim 1,540 feet apart. Sections of the bridge were lowered into place and then held back by steel tieback cables until the two sides of the arch could finally rest on each other high over the Colorado river. It is a beautiful bridge.
