description

Summary

Significance: Through its various permutations, the bridge exemplifies early Arizona bridge construction. First built in 1915-16 as a temporary timber trestle, it was upgraded in 1922 by the addition of two steel trusses, and later replaced entirely with the present concrete structure. It is significant as an integral part of U.S. Highway 80, arguably the state's most important east-west route. The bridge's completion in 1929 eliminated the last major obstacle to foul-weather driving on the route through Arizona. It is illustrative for its use of the four-rib concrete deck girder - a standard structural type in Arizona in the 1920s and 1930s. With its seven 45-foot girder spans, it represents one of the more noteworthy examples of its type in the state.
