All lanes of westbound Interstate Highway 580 have reopened this afternoon after a pair of big-rig collisions that turned fatal and blocked traffic for nearly 10 hours near Castro Valley in unincorporated Alameda

The collision was reported just east of Eden Canyon Road at 4:10 a.m., according to the California Highway Patrol.

A black sedan collided with a big-rig, affecting the driver's ability to steer the vehicle. The first big-rig came to rest in the middle of the freeway and was subsequently struck by a second big-rig, CHP Officer Tyler Hahn said.

The man driving the second big-rig died as a result of the collision, according to Hahn.

He's been identified as 62-year-old Maclovio Lopez of Roseville, according to the Alameda County coroner's bureau.

Personnel on the scene had to unload one of the trucks, which contributed to significant traffic delays.

A Sig-alert was issued at 4:24 a.m. because all westbound Highway 580 lanes were blocked. It was finally canceled around 2 p.m.
