All lanes now open on San Mateo Bridge

All lanes of westbound state Highway 92 are open now, following an accident involving three big-rigs this morning, California Highway Patrol Officer Tracy Hoover said.

Traffic in both directions is moving slowly this afternoon, Hoover said, but highway patrol officers at the bridge expect normal traffic patterns to resume by 3 p.m.

The accident occurred just before 7 a.m. on the San Mateo-Hayward Bridge when a big-rig struck a disabled big-rig on the right side of the highway, CHP Officer Mike Davis said. The tractor-trailer that struck the disabled big-rig then swerved sending its trailer into the Nos. 2 and 3 lanes. A third big-rig collided with the trailer, causing it to tip over and spill concrete onto the roadway.

The concrete that spilled on the roadway was mixed with lye, Davis said, so crews had to clean the roadway by hand instead of using motorized cleaning trucks.

“The concrete is not considered hazardous, but we don't want lye to be stirred up and blown into the Bay, or into people's lungs,'' Davis said.

Three people were injured in the accident, and one big-rig driver with life-threatening injures was transported by a Lifeflight helicopter to a local hospital. One other driver and a passenger in one of the tractor-trailers were taken to local hospitals with moderate injuries, Davis said. A third driver was not injured in the collision.

Units from the Foster City and Hayward fire departments, as well as CHP officers from both Hayward and Redwood City responded to the accident.
