A crash involving an overturned big-rig is expected to block lanes of Interstate Highway 680 in both directions in Walnut Creek until late this morning, a California Highway Patrol spokesman said.
The crash was reported around 6:35 a.m. on Highway 680 near North Main Street and has snarled morning commute traffic in the area, according to the CHP.
A Toyota Sienna minivan traveling north apparently got cut off and swerved to avoid a collision, spun out and ended up facing south, CHP spokesman Officer John Fransen said.
A big-rig carrying dirt swerved to avoid the Toyota but struck it, then continued through the concrete center dividing wall and overturned in the southbound lanes of the highway, causing damage to five cars that were traveling south, Fransen said.
Dirt and a small amount of diesel fuel spilled out of the truck and onto the roadway, he said.
The male driver of the big-rig and female driver of the Toyota were taken to the hospital with minor injuries, Fransen said.
The crash and spill initially blocked all southbound lanes and the two northbound lanes of Highway 680. The two far right southbound lanes have since reopened, Fransen said.
He said lanes will still be closed in the area until at least 11 a.m. because crews have to clean up the dirt, repair the center divider and remove the big-rig from the roadway.
CHP officials are asking anyone who may have witnessed what led to the crash to call their Contra Costa office at (925) 646-4980.
