All lanes of westbound Interstate 580 have reopened Thursday afternoon after a pair of big-rig collisions that turned fatal and blocked traffic for nearly 10 hours near Castro Valley in unincorporated Alameda County.
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.
Adding to delays in the area, Norris Canyon Road was temporarily blocked when a truck taking the road as an alternate to I-580 became stuck under a tree branch, according to the CHP.
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.
