History

SR 80 was originally conceived as part of the proposed state system of highway in 1919. In 1926, it became part of the cross-country highway US 80. The road was paved at this time between Douglas and Bisbee as well as a portion south of Tombstone. The remainder of the highway was a gravel road. By 1931, the highway was paved from Bisbee to the New Mexico state line as well as a portion south of Benson and another portion south of Tombstone. By 1934, the only portion of the highway yet to be paved was a section between Tombstone and Bisbee. The entire route had been paved by 1935. The highway would continue to serve as a portion of US 80 until 1989 when the last portion of US 80 in Arizona was removed. This portion of the highway was redesignated as SR 80 at this time.
