State Route 77: Gila River Bridge Replacement Project

The Arizona Department of Transportation is replacing the Gila River bridge on State Route 77 in Winkelman on the Gila/Pinal county line.

Work began in September 2019 and is scheduled to extend to the summer of 2021.

Traffic is restricted to a single lane in alternating directions using a temporary traffic signal, and a 15-foot vehicle-width limit is in place. Drivers should expect delays. 

In addition to a new concrete bridge, the project also includes guardrail and pavement markings.

Vehicles should proceed through the work zone with caution, slow down and watch for construction personnel and equipment.
