SAN LEANDRO — A motorcycle rider was killed and their passenger was hurt in a collision that closed some lanes of eastbound Interstate 580 for several hours, authorities said.
Around 1:15 p.m., California Highway Patrol officers responded to reports of the collision involving several vehicles, including a Nissan Murano SUV and a motorcycle, in eastbound I-580 lanes just before the 150th Avenue off-ramp.
Officers arrived to find at least three lanes blocked by several vehicles and debris. According to preliminary information, a Harley Davidson motorcycle with a rider and passenger entered the highway from the Grand Avenue on-ramp in San Leandro before colliding with the Nissan, which was stopped in traffic in the roadway’s right-hand lane.
Both rider and passenger were ejected onto the roadway’s open No. 3 lane, where a Ford Explorer struck the rider. The impact sent the motorcycle further east along traffic lanes, into a second motorcycle that was stopped in traffic.
Firefighters and paramedics responded to the collision and took the rider and passenger to Eden Medical Center in Castro Valley, where the rider was later pronounced dead. He was identified only as a 37-year-old Modesto resident, pending next-of-kin notification through the Alameda County Sheriff’s Office coroner’s bureau.
The motorcycle passenger was hospitalized with major injuries and was listed in stable condition, CHP Officer Daniel Jacowitz said.
The CHP issued a traffic alert at 1:46 p.m. urging drivers to avoid the area. The alert was lifted at 4:08 p.m.
There were no signs of alcohol or substances as collision factors, but investigators were working to determine whether speed or stop-and-go traffic conditions played roles.
Anyone with information may call the CHP’s Castro Valley office at 510-581-9028.
