Superior, Arizona — A scheduled bridge replacement will close a stretch of U.S. Highway 60 between Superior and Miami, triggering detours and potential travel delays.
According to the Arizona Department of Transportation (ADOT), US 60 will be closed between mileposts 227 and 243 from 9 a.m. to 2 p.m. Monday through Wednesday, March 17–19. The closure is required for construction work tied to a bridge replacement project along the corridor.
Transportation officials said the affected section sits between Superior and Miami, a key route connecting communities in eastern Pinal and Gila counties.
During the closure window, drivers will be directed to a roughly 75-mile detour through Winkelman.
For eastbound travel, motorists should take State Route 177 south to Winkelman, then continue north on State Route 77 to reconnect with US 60.
For westbound travel, drivers will instead take State Route 77 south through Winkelman and then north on State Route 177 back toward Superior.
ADOT estimates the detour could add approximately one hour of travel time for trips between Superior and Miami.
Because of the lengthy alternate route, transportation officials recommend drivers plan trips outside the closure window whenever possible, either before 9 a.m. or after 2 p.m.
The corridor is commonly used by commuters, commercial vehicles, and travelers moving between Globe, Superior, and Phoenix-area routes, meaning delays could affect regional traffic patterns.
Local traffic may still be allowed in limited areas near the work zone, but through travel will not be permitted during the closure periods.
Drivers are encouraged to check ADOT traffic alerts and allow additional travel time during the three-day construction window.
One note for younger drivers and commuters: the detour timing could impact students and workers traveling between communities in eastern Pinal and Gila counties during late-morning hours.
