Superior, AZ – Drivers traveling through eastern Arizona should prepare for delays as a key stretch of U.S. 60 will be shut down for several hours this week, impacting travel between Superior and Miami.
According to the Arizona Department of Transportation, US 60 will be closed from 9 a.m. to 2 p.m. Tuesday, March 24, between mileposts 227 and 243. The temporary closure is part of an ongoing infrastructure project to replace the Queen Creek Bridge, located just east of the existing structure.
Transportation officials said a new bridge is being constructed alongside the current one, which will be removed once the replacement is complete. In addition to the bridge work, crews will reconstruct the Waterfall Canyon Bridge near the Queen Creek Tunnel, converting it into two box culverts designed to improve drainage while maintaining its current location.
Detours will be in place during the closure window. Eastbound drivers will be redirected to southbound State Route 177 through Winkelman before reconnecting with northbound State Route 77. Westbound traffic will follow the reverse route, using State Route 77 to Winkelman and then northbound State Route 177.
Officials warn that the detour spans approximately 75 miles and could add up to an hour of travel time. Motorists are encouraged to plan ahead, adjust schedules if possible, or travel outside of the closure window to avoid significant delays.
The project is part of broader efforts to modernize transportation infrastructure in the region and improve long-term safety and reliability along the US 60 corridor.
