A 40-year-old Rodeo man has been identified as the victim in a fatal motorcycle collision on eastbound Interstate 980 on Sunday morning in Oakland.
Steven Lee was pronounced dead at the scene, according to officials from the Alameda County coroner's bureau.
The collision was reported at around 2:06 a.m. near the 27th Street onramp, according to California Highway Patrol officials.
The collision involved a car and a motorcycle and blocked off the transition from eastbound I-980 to eastbound I-580, CHP officals said.
A Sig-alert was issued at 2:32 a.m. and was canceled at 4:42 a.m.
Although the incident was initially reported as a hit-and-run, CHP officers are working to positively determine if any other vehicles were involved in the collision.
Witnesses said a dark van made an illegal lane change and clipped the back of Lee's bike, causing him to crash. The CHP did not confirm there was such a vehicle involved.
Anyone who may have seen the motorcyclist just before the collision or who witnessed the collision is asked to contact the Oakland CHP office at (510) 450-3821 or (707) 551-4196.
