Byron, CA – A Brentwood man has been identified as the victim in a fatal motorcycle crash that occurred early Monday morning near Byron, authorities said.
The Contra Costa County Sheriff’s Office identified the motorcyclist as Curtis Carr, 54, who crashed while riding along Vasco Road just north of Dyer Road, near the Contra Costa–Alameda county line.
According to the California Highway Patrol, Carr was traveling southbound on Vasco Road at approximately 5 a.m. when he lost control of his motorcycle. Investigators said the motorcycle crossed into the northbound lanes and struck a guardrail, ejecting Carr down an embankment.
Carr was pronounced dead at the scene. Emergency responders took more than 20 minutes to locate him due to the terrain below the roadway, officials said.
CHP reported that the motorcycle continued rolling after the initial impact and eventually came to rest in the northbound lane, blocking traffic.
The crash caused significant traffic delays on Vasco Road for nearly three hours.
The cause of the accident remains under investigation. No additional vehicles were reported to be involved.
