Problems with the Isthmus Slough Bridge include extensive cracking and exposed rebar on the deck of the westerly approach spans, pack rust in the truss elements, broken welds and missing bolts. The electrical and mechanical systems of the drawbridge are old and require frequent repair.
This project will repair and resurface the deck, modify the deck drains, reconstruct expansion joints, seal cracks on the concrete surface of the bridge, repair welds, replace bolts, remove rust, and replace the electrical system.
