The Rio Vista Bridge became inoperable on August 9, 2018 when the bridge lift span gear assemblies were damaged. Initially the bridge was stuck in the up position impacting vehicular traffic until it was lowered after several days, which in-turn impacted the maritime traffic. The bridge is a regionally significant commerce passageway, as it represents the only way for cargo ships to get in and out of the Ports of West Sacramento and Stockton.


The purpose is to provide for immediate/emergency repairs and improve reliability of the bridge electrical and mechanical operational systems. It also includes assessing and repairing and/or upgrading mechanical and electrical components (motors, gears, powered backup systems, lift cables, ropes, power and communication lines, modern control systems, etc.); Expert and peer review to advise designers and contractors on systems and repair methods; Upgrading signage and lighting; and placing a new lightweight bridge deck on the lift span.
