A 70-year-old Foster City man died Wednesday evening after his car drifted off the road on southbound Interstate Highway 680 in San Ramon and hit a eucalyptus tree, a California Highway Patrol officer said.
The man suffered severe injuries and was taken to the San Ramon Regional Medical Center, where he was pronounced dead, CHP Officer Ralph Caggiano said.
The crash occurred just before 3:50 p.m. as the man was driving in the No. 2 lane north of Crow Canyon Road, CHP Officer Steve Creel said.
Witnesses saw the man's vehicle, a 1984 Cadillac Eldorado begin to drift to the right, Creel said. It traveled across three lanes of traffic and went another 50 or 60 feet off the road before hitting a eucalyptus tree.
The man was unresponsive when paramedics reached him and he was transported to the hospital, Creel said.
