A motorcyclist killed in a head-on crash on state Highway 35 in southern San Mateo County on Thursday afternoon has been identified by the county coroner's office as 23-year-old Fremont resident Dong Chen.
The collision was reported around 1:45 p.m. on state Highway 35 about a quarter-mile south of Page Mill Road, according to the California Highway Patrol.
Chen was pronounced dead at the scene about 15 minutes later, CHP Officer Amelia Jack said.
Investigators believe the motorcyclist was traveling south and crossed over into the northbound lanes, where he struck the front of a black Acura driven by a Mountain View resident, Jack said.
It does not appear that drugs or alcohol played a role in the crash, Jack said.
The highway was closed in both directions until around 4:15 p.m.
Anyone who witnessed the crash is asked to call the CHP at (650) 369-6261.
