A motorcyclist died early Wednesday after a freeway crash that also involved at least one vehicle, according to the California Highway Patrol.
The crash first was reported about 7:12 a.m. It happened in the eastbound direction of Interstate 580 just east of the Grove Way exit.
Authorities did not identify the person immediately. Alameda County Coroner’s Office personnel were on their way to the scene.
The crash blocked all but the far left lane of the five-lane freeway. The CHP issued a Sig-alert or severe traffic at 7:29 a.m., and did not have an estimate for when it would be lifted.
