Caltrans will shut down the San Mateo Bridge in both directions for repairs on the last two weekends in October, and the agency is advising motorists to plan accordingly.

The closure will enable crews to perform a long-term fix on a crack that was found during a routine inspection in October 2010 on a wishbone-shaped support beam underneath the roadway.

The bridge will be closed from 10 p.m. Oct. 19, through 5 a.m. Oct. 22, and again from 10 p.m. Oct. 26 through 5 a.m. Oct. 29.

The shutdowns will increase traffic on other bridges during those weekends, so Caltrans is recommending that travelers take public transportation or carpool when possible and plan for longer trips. The Dumbarton Bridge will be the best alternative for people driving across the bay, said Caltrans spokesman Bob Haus.

Caltrans workers will install a new seismic joint and replace 60 feet of concrete bridge deck just east of the high rise on the San Mateo County side of the seven-mile span. The job will cost $3 million, about three times as much as the 2010 work. Though temporary, the previous fix made the bridge safe, said Haus.

"The repair we did is holding up," he said. "We go up there continually and check."

Caltrans is reaching out to Bay Area sports teams to get the word out to people attending games on the weekends the bridge will be closed. The agency will also be putting up signs throughout the region to alert motorists to the closure.
