One person was killed in a chain-reaction crash just before midnight Thursday on Interstate 680 in San Ramon.
The crash was first reported at around 11:25 p.m. near the Bollinger Canyon Road off-ramp, according to the California Highway Patrol.
Officers reported that a southbound black Honda sedan rear-ended a crane-equipped utility truck – and was moments later struck by yet another car that crashed into it.
The driver of the Honda was killed in the crash. A driver in the second car was hurt but not seriously, officers said. The crash temporarily closed the two southbound “slow” lanes of the highway while investigators worked to determine the cause of the crash. All lanes were reopened shortly before 6:30 a.m., CHP said.
