A man who died Saturday morning in a solo-vehicle crash on a transition ramp from southbound Interstate Highway 680 to eastbound Interstate Highway 580 in Pleasanton has been identified as 64-year-old Dublin resident Michael Chapman.
California Highway Patrol officials said Chapman , 65, was driving a white Ford F-350 pickup truck with a raised frame when he lost control of it and hit some attenuator barrels between the transition ramp and the Hopyard Road off-ramp.
CHP Officer Derek Reed said the Ford hit the barrels at a high rate of speed, went over a guardrail and the front of the truck crashed into a freeway overpass abutment. The Ford came to rest on a guardrail.
Chapman was pronounced dead at 7:48 a.m.
One lane of the transition ramp was closed until about 10 a.m. The Hopyard Road exit ramp reopened at 2:30 p.m. after road crews made some repairs and replaced the attenuator barrels.
