A Berkeley woman was killed in a solo-motorcycle crash on Interstate Highway 80 in Richmond on Thursday night, according to the California Highway Patrol.
The motorcyclist was riding a 1992 Kawasaki motorcycle in the far right lane of westbound I-80 at 8:51 p.m. when she lost control and struck a metal guardrail on the right shoulder just west of Carleson Boulevard.
The impact launched the rider over the guardrail, and she was found in the trees and shrubs on the right side of the guardrail, the CHP said.
The motorcycle slid and came to rest in the right lane.
A witness told investigators that the motorcycle was going at least about 60 mph, but it did not appear that the rider was speeding, according to the CHP.
The victim was identified as 41-year-old Berkeley resident Dayna Seico.
The right lane of the highway was closed until shortly after 11 p.m. while the CHP investigated the crash and the coroner removed the body.
