RIO VISTA -- Caltrans is advising motorists of six scheduled weekend closures of the Rio Vista Bridge (Helen Madere Memorial Bridge) on State Route 12 (SR 12) for ongoing repairs.
This $27.2 million project is funded through the Bridge Rehabilitation and Replacement Program and will require multiple 5
6-hour weekend closures for the work to be completed because of the limited width of the bridge to allow for heavy equipment access.
The project is making necessary mechanical repairs, replacing the movable deck span and replacing bridge rails. Completion is expected late this summer.
During the weekend closures that are scheduled between March and June, the contractor will replace the movable span bridge deck concrete, and 60 steel stringers needed to extend the service life of the bridge.
Due to the limited width of the exiting bridge deck, 56-hour weekend bridge closures are necessary to facilitate safe access to the work for contractor and Caltrans personnel. The weekend bridge closure schedule will lessen total project workdays and help avoid long wait times at peak commute hours during the week.
