Big-rig driver dies when truck crashes into tree in San Ramon

SAN RAMON, Calif. (BCN) - A big-rig driver died when his truck went off a highway and into a tree this morning in San Ramon, California Highway Patrol officials said.

Someone called the CHP at about 7 a.m. to tell them that a big-rig went off southbound Interstate Highway 680 just north of Alcosta Boulevard and clipped a vehicle on the right shoulder of the highway.

CHP spokesman Officer Tyler Hahn said the truck continued through a fence and into a tree.

The occupants of the vehicle clipped by the big-rig were not hurt.

CHP officials said the crash has closed northbound San Ramon Valley Road between Alcosta Boulevard and Pine Valley Road because the truck came to a stop on San Ramon Valley Road.

CHP officials do not have an estimate for when San Ramon Valley Road will reopen.
