Multi-car crash on Bay Bridge injures one.

An injury crash blocked multiple lanes on the lower deck of the Bay Bridge for about 40 minutes this morning, according to the California Highway Patrol.

The crash was reported at about 9:20 a.m. and involved four cars in the eastbound lanes of the bridge near Treasure Island, CHP Officer Kevin Bartlett said.

At least one person suffered minor injuries in the crash, which initially blocked the four left eastbound lanes, Bartlett said.

Two of the lanes opened by about 9:50 a.m. and the roadway fully reopened about 10 minutes later, according to the CHP.
