State Route 76 ran from SR 77 to Peppersauce Wash with a second, disconnected segment from Benson to Pomerene. The original plan for the highway was to have a complete connection between Benson and San Manuel, used to serve the San Manuel Copper Mine, and the communities in between. Various county roads were used in the planning of this highway and some grading work was done where a new road was going to be built. Some bridges were also built along the route, named the San Pedro River Bridge, Redfield Canyon Bridge, and the Tres Alamos Wash Bridge. These bridges were never officially designated as a part of SR 76, however. In 1974, the northern segment of SR 76 north of San Manuel from SR 77 to the old open pit mine was removed from the state highway system and the full route was later canceled in 1988. This more detailed information about SR 76 is available thanks to this AARoads forum post by 707, who has done a lot of research on the route's history.
