Arizona Department of Transportation issued the following announcement on July 19.
Full overnight closures are scheduled on US 60 between Miami and Superior Wednesday, July 21, and Wednesday, July 28, as part of the Pinto Creek Bridge replacement project.
The Arizona Department of Transportation will close the highway between 8 p.m. and 4 a.m. on July 21-22 and July 28-29 while crews pour the concrete deck on the new bridge. While the highway is scheduled to reopen at 4 a.m. the following Thursday mornings, drivers may encounter alternating lane restrictions and flaggers directing traffic if work extends past that hour.
During the closure, US 60 traffic will be detoured to SR 177 in Superior and SR 77 in Globe. The detour includes a 10% grade and will significantly increase travel time. Traffic will not be allowed to queue at the closure locations.
Motorists on US 60 with a destination between SR 177 and Top-of-the-World west of Pinto Creek or between Miami and Pinto Valley Mine Road east of Pinto Creek will be allowed to pass. However, no vehicles will be allowed between Top-of-the-World and Pinto Valley Mine Road.
