A man was hospitalized Sunday night following a three-vehicle accident at the Bollinger Canyon Road offramp from Interstate Highway 680, San Ramon police said.
Police Cpl. Mike Pistello said that at about 8:10 p.m. Sunday, a car came off southbound I-680 at Bollinger Canyon Road, apparently at a high speed. That vehicle slammed into a car near the Bollinger Canyon Road overcrossing, which in turn was shoved into a third vehicle, Pistello said.
An occupant of the first vehicle, an adult man, was taken by ambulance to John Muir Medical Center in Walnut Creek, a regional trauma center. Pistello could not comment on the nature or severity of that man's injuries.
At least one other person was examined at the scene for minor injuries.
Though it appears excessive speed was a contributing factor in this accident, Pistello said its cause remains under investigation.
