All lanes are open Wednesday morning after a fatal collision that blocked multiple lanes of the westbound Bay Bridge just west of the toll plaza, according to the California Highway Patrol.
At about 4:30 a.m., the CHP received a call about a collision between a box truck and a Golden Gate Transit bus just east of Treasure Island, according to CHP spokesman Officer Bert Diaz.
Three people were in the box truck, which rear-ended the bus as it was coming to a stop, Diaz said. One of the passengers in the truck died at the scene and two others were taken to a hospital with serious injuries.
Golden Gate Transit spokeswoman Priya Clemens said two passengers on the bus — a BART bus bridge en route from MacArthur Station in Oakland to the Transbay Transit Center in San Francisco — were transported to a hospital.
Diaz said 40 gallons of diesel fuel had spilled and Caltrans crews responded to clean it up.
Three lanes of the five-lane bridge were blocked for hours, snarling the morning commute into San Francisco. All lanes were opened by about 9:30 a.m., according to the CHP.
In response to the collision and subsequent lane closures, BART announced that it was extending the number of the longer commuter trains it runs in the morning. As of about 8:45 a.m., about 4,000 additional passengers had made the trip to San Francisco via BART compared to the average weekday.
