RIO VISTA – Caltrans is alerting recreational boaters and commercial shipping that the Rio Vista Bridge on State Route 12 is scheduled for waterway closure to large vessels and sailboats needing bridge lifts next week. The bridge will remain in the down position.

The bridge remains safe for travel. A Caltrans contractor and structural engineers will install a new permanent backup drive system to help address the overall reliability of the drawbridge that includes electrical, counterweight balancing and bridge lift testing.
