About the Rio Vista Bridge Preservation Project
The $37.1 million project includes cleaning and painting the drawbridge on State Highway 12 over the Sacramento River in Rio Vista. This work is scheduled to take three years. All work will be performed under traffic control and the bridge will remain open at all times. One of the walkways will be open to pedestrian-bicycle traffic around the clock.
The contractor must accommodate the drawbridge operation at all times. The U.S. Coast Guard requires commercial and recreational vessels to provide four-hour advance notice to raise the drawbridge.
The daily weekday construction schedule with one-way traffic control is from 7 p.m. to 6 a.m. Monday through Thursday and 8 p.m. to 9 a.m. Friday. Weekend shifts are scheduled as needed from 9 p.m. Saturday to 10 a.m. Sunday. (All work is weather dependent.)
The Rio Vista Bridge Preservation Program involves two construction projects. The first project is underway and calls for cleaning and painting the drawbridge. The existing coating system is deteriorating at various locations of the bridge. Completion of this $37.1 million project is expected in winter 2020.
The Rio Vista Bridge, officially named the Helen Madere Memorial Bridge, is located in Sacramento and Solano counties, about one-half mile from the Highway 12/Highway 160 junction. The vertical lift bridge was built in two stages between 1943-1945 and 1957-1960. It carries about 23,000 vehicles per day.
The second project, which will cost an estimated $11.9 million to $19.2 million, will upgrade the mechanical and electrical operation of the bridge. Work is tentatively scheduled to start in spring 2022 and take two construction seasons to complete. This schedule is subject to change.
