DANVILLE -- At least one person was injured in a multicar crash that slowed late-hour commuters Wednesday, the California Highway Patrol said.
Officers responded to northbound Interstate 680 at the Sycamore Valley Road off-ramp and found at least one person trapped inside a vehicle. Two cars suffered major damage, the CHP said, and one person was transported to Kaiser in Walnut Creek with unknown injuries.
All but one northbound lane is closed on I-680, and an estimated time of reopening for all other lanes is unknown.
Drivers can expect major delays.
