One person was seriously injured Tuesday morning when a car crashed down a cliff off of Skyline Boulevard in Daly City, a California Highway Patrol spokesman said.

The crash was reported on southbound Skyline Boulevard, which is also state Highway 35, near Olympic Way at about 4:20 a.m., CHP Sgt. Steve Shirer said.

A Dodge Charger left its lane and traveled about 300 feet down a steep dropoff on the western side of the roadway, Shirer said.

A man in the car was seriously injured, and southbound lanes were closed for more than an hour while rescue crews extracted him from the wreckage, Shirer said.

Fire crews set up a cliff rescue operation, using a winch to gain access to the vehicle. The victim was taken to a hospital and is expected to survive, he said.

A second occupant of the vehicle was not injured.

Skyline Boulevard reopened to traffic at about 5:30 a.m., though crews remained at the scene and the vehicle had not yet been towed back to the roadway as of 8:30 a.m.

The crash remains under investigation by the CHP.
