RICHMOND -- Authorities say a motorcyclist chose to ride home after a crash at Stinson Beach on Thursday, but was killed after he slumped over his bike and veered off Interstate 580 Thursday afternoon near Castro Street in Richmond.
No one else was injured.
At 3:24 p.m., California Highway Patrol officers responded to calls of a motorcyclist down near eastbound I-580 on the Castro Street off-ramp. When officers arrived, they found a motorcycle blocking the roadway on Castro Street at Tewksbury Avenue with the rider lying adjacent to the motorcycle.
Richmond Fire Department crews and paramedics attempted to revive the man, but he succumbed to his injuries on scene, said CHP officer Daniel Hill.
A man who was riding on another motorcycle with the victim told officers that the motorcyclist had crashed at some point earlier in the day near Stinson Beach. Despite saying he did not feel well, the motorcyclist decided to continue riding to his home in Richmond, Hill said.
At the Castro Street exit, for unknown reasons, the motorcyclist veered to the right and slumped over the handlebars of the motorcycle.
The man, who authorities say is a Richmond resident, has not been identified pending notification of his family.
