Mare Island Causeway Bridge Repair Work

under construction

Repair work on the Mare Island Causeway Bridge in Vallejo is underway to extend the bridge's life and enhance pedestrian and driver safety. The project includes maintenance repairs, painting of lift towers, installation of light posts and poles, guardrail post installation, handrail painting, and work beneath the bridge deck and on the deck surface. The project is temporarily delayed due to nesting activity of the California Black Rail, a threatened native species, and other issues such as cable conflicts, weather, and materials.
