Significance: It is noteworthy as one of the last remaining spans from the San Carlos Bridge, a large-scale wagon truss built over the Gila River by the Office of Indian Affairs. Completed in 1913, it is technologically significant as the earliest documented example in Arizona of a mainstay structural type: the riveted Pratt through truss. It is historically important as one of the earliest multiple-span wagon bridges erected in Arizona by the Federal government. It is also infamous for its failure. Washed out a year before its completion, it stood abandoned for some six years before it was repaired and reopened. After that, the structure then carried traffic for only 14 years before it was replaced entirely and the individual spans distributed around the state.
