A person was killed after a two-vehicle crash just west of the Bay Bridge toll plaza.
Several eastbound lanes of the Bay Bridge were closed as NBC Bay Area's Emeryville camera showed a large backup.
Just before 9 p.m., California Highway Patrol said that their officers responded to a report of a collision involving a small sedan that veered off the right-hand side before overturning. A second vehicle was found sideways in the slow lane.
Despite emergency life-saving measures, the person was pronounced dead at the scene, CHP said.
