The Glen Canyon Bridge or Glen Canyon Dam Bridge is a steel arch bridge in Coconino County, Arizona, carrying U.S. Route 89 across the Colorado River. The bridge was originally built by the United States Bureau of Reclamation to facilitate transportation of materials for the Glen Canyon Dam, which lies adjacent to the bridge just upstream. Carrying two lanes, the bridge rises over above the river and was the highest arch bridge in the world at the time of its completion in 1959. ==See also==
