Livermore Man Driving 90 MPH Dies In I-580 Off-Ramp Crash

LIVERMORE, CA — A 45-year-old Livermore man was killed in a solo overturn crash on a westbound I-580 off-ramp in Livermore Tuesday night, according to the California Highway Patrol.

At around 8:42 p.m., CHP officers arrived to find a convertible 2003 Audi A4 on a grass field just south of the Isabel Avenue off-ramp, according to a department news release. An on-scene investigation determined that the driver was traveling at speeds of roughly 90 mph before exiting. Authorities said the Audi made an "aggressive" maneuver to pass a slower-moving Honda on the off-ramp, and in so doing lost control of the car. The Audi then launched off the off-ramp and overturned multiple times down the south side embankment.

The driver of the Honda stopped at the scene and cooperated with authorities.

The Alameda County Coroner's Bureau confirmed the man's identity as Jonathan Walker, 45, of Livermore.

Police say they are currently investigating whether alcohol impairment played a role.

The off-ramp was closed for over three hours Tuesday night to gather physical evidence and recover the car.
