The Mare Island Causeway Bridge, originally built in 1934, is a vehicle and pedestrian bridge that straddles the Napa River and serves as the connector between the Greater Vallejo area and Mare Island. In 2016, the City completed an upgrade project on the Bridge, replacing a 50-foot span of bridge timber with steel. The iconic Bridge requires additional maintenance repairs to extend the Bridge's serviceable life and improve pedestrian and driver safety. These repairs are expected to include:


• Bridge deck and pile repairs

• Sidewalk replacement and ADA improvements

• Lighting and handrail repairs

• Repainting the Bridge's steel lift span, towers, and historic logo

• Deck methacrylate coating (Painting)

• Concrete spall and crack repairs

• Fender system repair for marine traffic safety

• Replacement of underwater anodes
