Caltrans is advising motorists of a scheduled closure of the Rio Vista Bridge (Helen Madere Memorial Bridge) on State Route 12 (SR-12) just east of the City of Rio Vista due to a paving project. The 55-hour weekend bridge closure schedule will lessen total project workdays and help avoid the wait times during peak commute hours during the work week. Motorists could encounter additional travel times of up to two hours using detours from Rio Vista to Sacramento County on SR-12 across the Sacramento River. Please allow for extra travel time to reach your destination, especially for scheduled appointments and work schedules. Anticipate 3 weekend closures this Fall, beginning in mid-October on a staggered schedule through November. All work on road construction projects will be suspended on weekends and holidays. Schedules are subject to change due to weather conditions, equipment or material availability, or other unexpected events. The $11.24 million project through the Bridge Rehabilitation and Replacement Program will require multiple 55-hour weekend closures for the work to be completed. The project will make necessary bridge repairs and updates by rehabilitating the roadway surface, placing polyester concrete overlay on the bridge deck, replacing bridge rails, installing bridge approach slabs, and constructing Americans with Disabilities Act (ADA) compliant switchback ramps. These upgrades will improve motorist and non-vehicular bridge users' safety, restore bridge deck integrity, comply with ADA accessibility requirements and expand access for pedestrians and non-motor vehicles, and improve the overall ride quality. The department will issue construction updates on X (@CaltransDist3) and on Facebook (CaltransDistrict3). Caltrans reminds motorists to "Be Work Zone Alert" and slow in construction zones for the safety of travelers and crews performing these improvements. Visit bit.ly/CTDeltaRegion for more information.
