Rio Vista Bridge to be closed Thursday evening through Friday morning for testing

The Rio Vista Bridge will be subject to one-way traffic controls on Sunday.

The Rio Vista Bridge, which connects Solano and Sacramento counties on state Highway 12, will be closed today at 7 p.m. until 5 a.m. Friday as Caltrans crews continue to complete work on the drawbridge.

The bridge was shut down for a short time last week after it got stuck in the upright position on Aug. 9 and reopened Friday night. according to Caltrans officials. It will be closed again as crews manually test and raise the bridge overnight.

Caltrans officials said the mechanism that raised the bridge was damaged last week. The part, a damaged motor gearbox, has been sent to a manufacturer for expedited repairs.

Caltrans and the U.S. Coast Guard will schedule future marine traffic once the bridge is raised, Caltrans officials said.

Alternate routes around the traffic restrictions are the ferries on state Highways 84 (Real McCoy) and 220 (Ryer Island). Motorists can also take Interstate Highway 80 eastbound to Sacramento and travel south on Interstate Highway 5 or take southbound Interstate Highway 680 to eastbound 
state Highway 4.
