HAYWARD -- A four-vehicle crash involving a semi-truck sent one person to the hospital on Monday morning and backed up traffic along the San Mateo Bridge for more than an hour, according to the California Highway Patrol.
Officers were called at 8:27 a.m. to the eastbound lanes of the bridge for a report of an injury crash, said Officer Kevin Bartlett.
When officers arrived on scene they learned four vehicles -- a semi, a Mazda and two other cars -- got into a wreck, Bartlett said.
At the scene, the semi-truck appeared to have hit a middle rail on the bridge and sustained damage on its front left side. A car behind the semi, a sedan, was crushed on the front end.
The cause of the wreck was not immediately known.
One person was taken to a hospital to be treated for minor injuries, Bartlett said.
All lanes of traffic were shut down for a short period of time, he said, but were reopened by officers about 9:50 p.m.
