Multi-vehicle crash midspan on San Mateo Bridge blocks lanes in both directions

FOSTER CITY — CHP have issued a special traffic alert Friday afternoon following a collision involving four vehicles in eastbound lanes of Highway 92 on the San Mateo Bridge that for a time blocked lanes in both directions.

The alert was issued at about 3:45 p.m. after the crash blocked the left and center lanes midspan, authorities said. Traffic in the eastbound direction was only getting by in the one remaining open lane, causing a major back-up.

Responding emergency crews were also blocking the left lane in westbound direction, according to a Caltrans image that was shared by the KCBS Traffic Twitter account.

Shortly after 4:15 p.m., the emergency vehicle that was blocking the westbound lane had cleared the scene. Motorists are advised to expect delays and to use alternate routes to avoid the area. There is no estimated time to reopen the roadway.
