State Route 4 Garwood Bridge Rehabilitation Project
Public Notice
Project Description
The California Department of Transportation proposes to address the structural deficiencies on the existing San Joaquin River Garwood Bridge (Bridge Number 29-0050). The proposed work includes replacing the damaged members of the west portal sway truss bracing with new members, removing the bridge operator house, patching the spalls in the polyester concrete overlay along the westbound lane and along the soffit of Bay 4 in Span 3, and resetting the bridge abutment bearing to prevent the undesirable movement occurring in the right bearing at Abutment 1.
