It formerly went east to the New Mexico border near Lordsburg, but this eastern segment has been superseded by Interstate 10. SR 86 is the primary east–west highway through the Tohono O'odham Nation. Note that this route is commonly blocked off by US Department of Homeland Security Border Patrol Agents to perform random searches of vehicles, due to its
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.
