SR 80: San Pedro Bridge Replacement Project in St David

The Arizona Department of Transportation is performing a bridge repair project on State Route 80 in St David, AZ, spanning over the San Pedro River. The work will consist of removing the existing San Pedro River Bridge and replacing it with a continuous three span welded steel plate girder bridge. Additional work includes replacing guardrail and placing pavement markings.

One travel lane will remain open at all times.
Traffic will be shifted during construction to allow crews to work on one side of the bridge at a time. Alternating lane restrictions will begin Wednesday, Dec. 14, 2022.
Temporary traffic signals at bridge access points will be used to regulate traffic in each direction.
A 10-foot vehicle width restriction will be in place.
