Delta Region Scheduled for More Traffic Interfering Work

State Highway 12 Rio Vista Bridge Preservation Project to Begin by late January 2018

SACRAMENTO AND SOLANO COUNTIES– Caltrans announced today that a major project to preserve the Rio Vista Bridge on State Highway 12 in the Delta region will be moving forward as planned.

The heavily travelled corridor is expected to experience serious traffic delays when nighttime construction work begins in January, 2018. One-way traffic control will be used to regulate the eastbound and westbound directions for Highway 12 into the early morning hours.

The existing coating system on the Rio Vista Bridge is deteriorating at various locations. Although the bridge is still safe for travel, there are rust spots at different areas along the truss, tower, and floor system members, and rusting around many of the truss gusset plate nuts and bolts. The purpose for the estimated $37 million project is to make the necessary repairs to the damaged areas of the bridge, sand blast the old coating and re-paint the bridge.

Job bids for this project were received in early September and the contractor should be decided on in the next few weeks, possibly by early October. A work schedule will be established after the contractor is hired.

The project is estimated to take from three to five years to complete. Daytime work cannot be performed because the U. S. Coast Guard requires the bridge to remain open for maritime traffic and the traffic data indicates there would be serious delays for motorists traveling on Highway 12 and State Highway 160 just east of the bridge. Additional public outreach meetings are scheduled for this fall.

Caltrans advises motorists to “Be Work Zone Alert.” The department will issue construction updates on Twitter @CaltransDist3 and on Facebook at CaltransDistrict3. For real-time traffic, visit QuickMap at or download the QuickMap app on iTunes or Google Play.
