Freeway traffic on I-580 was delayed for some time after a truck accident involving a semi tractor-trailer. According to police, three cars were involved in the accident. One of the cars was pushed by the big rig truck into a fence adjacent to the train tracks. The tracks are used by the Bay Area Rapid Transit System commonly known as BART to deliver passengers to and from the San Francisco area.
California Highway Patrol Officers responded to the mid-afternoon crash, officers on the scene reported that the driver of the semi tractor-trailer, which was hauling a load of dirt at the time, did not see a car changing lanes in front of the truck. The truck hit the car pushing it into two other cars that were also traveling in the same direction on the freeway. The big rig and two of the cars involved in the accident smashed into the center divider on the highway.
Three of the individuals involved in the crash were transported to the Eden Medical Center where they were treated for minor injuries.
BART trains used just one track through the accident area. Train traffic through the scene was slowed while rescue workers and clean-up crews treated the injured and removed the truck and cars disabled in the crash. Trains heading into San Francisco and Daly City were not affected by the accident.
Two of the eastbound lanes on I-580 were blocked by debris and had to be closed for more than two hours to allow for clean-up.
