A bicyclist was taken to the hospital with major injuries after colliding with a vehicle in the Dougherty Valley on Saturday afternoon, according to the San Ramon Police Department.
Multiple calls came to the San Ramon Valley 911 Communications Center around 2:50 p.m. Saturday to report a vehicle collision involving a bicyclist on Dougherty Road just north of North Monarch Road, according to San Ramon police Lt. Tami Williams.
The vehicle was driving northbound on Dougherty Road in the right-most lane at an unknown speed while the bicyclist was also traveling northbound on Dougherty. Preliminary investigation indicates the bicycle was within the bike lane at the time of the collision, Williams said.
The primary cause of the collision is still under investigation, Williams said. The bicyclist sustained unspecified serious injuries and was transported to an area hospital for treatment.
The driver of the vehicle cooperated with police, and neither drugs nor alcohol appeared to have been a factor based on the preliminary investigation, according to Williams. The identities of the involved parties were not released.
"The San Ramon Police Department's Traffic Unit is conducting a thorough investigation of this incident," said Williams, who encouraged any potential witnesses to contact San Ramon PD at 925-973-2700.
The intersection of Dougherty and North Monarch roads was closed for several hours during the police investigation and crash cleanup.
