The bridge was designed by the Arizona Highway Department in a process beginning in 1927. The design chosen was a multi-span concrete slab-and-girder structure. It would require 2000 cubic yards of concrete and 146,000 pounds of steel. String and Grant of Springville, Utah, was the low bidder of four contractors seeking the work, with bid of $47,325, and the firm built the bridge during January to July 1929.[2]

The bridge had seven spans, each 45.7 feet (13.9 m) long, with total length 319.6 feet (97.4 m) and roadway width of 24.2 feet (7.4 m).[2]

U.S. Route 80 was later realigned to a different route, and the bridge was a county road bridge in 1987.[2]

The bridge was deemed significant as "a representative example of reinforced concrete technology as practiced by the Arizona Highway Department". It was an "important" bridge on U.S. 80, an early transcontinental route, and "Arizona's most heavily trafficked highway".[2]

The bridge was documented with drawings and photographs by the Historic American Engineering Record.[3]

The bridge was scheduled for demolition in 1993.[3]

The bridge was modified and repaired in 1993.
