WALNUT CREEK -- All lanes of Interstate 680 reopened nearly five hours after a big-rig overturned and snarled Thursday morning's commute in Contra Costa County, the California Highway Patrol said.
The CHP opened all southbound lanes of traffic about 11 a.m., after clearing the vehicle and removing a fuel spill from the roadway.
The truck's driver suffered head and neck injuries in the crash, which took place just before 6:35 a.m. near North Main Street. The big-rig, carrying dirt, was traveling north on I-680 when it overturned and part of the vehicle ended up in the interstate's southbound lanes, CHP Officer Eric Anderson said.
The crash initially shut down all southbound lanes as well as the two far left northbound lanes of the busy freeway. Motorists were diverted around the wreck onto North Main Street, Anderson said.
The lanes were closed until about 11 a.m. so a tow truck could remove the overturned rig. Hazmat crews also responded to the scene to clean up the fuel. It wasn't immediately known how much fuel was spilled.
The crash also caused significant damage to the center concrete barrier on the freeway. California Department of Transportation crews responded to the scene to address that damage.
