Below is a list and summary of the former state routes in Arizona, including mileage tables and maps. Between the establishment of Arizona's numbered state highway system in 1927 and the present date, several state routes have been decommissioned. Some state routes were retired as a result of the state relinquishing ownership to local authorities, while others were made extensions of or redesignated as other highways, with some former state routes being upgraded to U.S. Highway or Interstate status.
