The Arizona Department of Transportation is replacing the Gila River bridge on State Route 77 just south of Winkelman on the Gila/Pinal county line.
Work is scheduled to begin in the fall of 2019 and extend through the summer of 2021.
Traffic will be restricted to a single lane in alternating directions using a temporary traffic signal. Drivers should expect delays.
A vehicle width limit of 15 feet will be in place for much of the project.
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.
