HAYWARD — A four-vehicle pileup caused by a disabled vehicle brought traffic to a crawl on Interstate 880 Friday morning, according to the California Highway Patrol.

Traffic was backed up in both directions near A Street in Hayward because of the crash on southbound lanes and a highway sign that fell onto northbound lanes, the CHP said.

Authorities said it all began when a driver abandoned a disabled car at about 3 a.m. A street sweeper vehicle crashed into the car, causing a big rig carrying wine to swerve and overturn, blocking all lanes and knocking a sign down on northbound lanes, according to the CHP. Next, a driver of a Ford CMax crashed into the big rig.

Three southbound lanes were closed until 10:05 a.m. Northbound lanes were also closed until 7:59 a.m.

Authorities were looking for the driver of the disabled car who was gone by the time officers arrived. Two drivers and a passenger were injured, the CHP said.

Commuters headed to Marin County on the Richmond Bridge were also slowed by a big rig that spilled fuel on the lower deck of the bridge at about 6:49 a.m., CHP Officer Eric Anderson said.
