Arizona State Route 80 Arizona State Route 80 State Route 80 (SR 80) is a roughly arc-shaped highway lying in southeastern Arizona that, with New Mexico's State Road 80, is a relic of the old U.S. Route 80, now truncated from San Diego to Dallas. This segment of old US 80 was not closely paralleled by Interstate 10, which lies to its north, and instead supplants the old and more direct (defunct in eastern Arizona) State Route 86. The route begins at an intersection with I-10 Bus. in Benson near an Amtrak station. The route heads south until it exits the city limit of
Arizona State Route 260 eastern Rim. It is also closed during winter storms because of its elevation changes between Payson and Show Low. SR 260 was originally designated in 1955 as SR 160 from Payson to Show Low. In 1969, US 160 extended into Arizona, so SR 160 was renumbered to SR 260 to avoid confusion. In 1972, it extended east to Eagar, replacing SR 173 and part of SR 73. On December 15, 1989, SR 260 extended west to Cottonwood over SR 279.
