Overturned Big Rig Spill Prompts Hourslong Closure of SB 710 Freeway Near Commerce

Spilled antifreeze from an overturned big rig forced an hourslong closure of the southbound 710 Freeway near Commerce Thursday morning.

The solo-vehicle crash was reported about 1:45 a.m. just north of the 5 Freeway, according to the California Highway Patrol’s traffic incident log.

The driver told investigators he was unable to maintain control of the vehicle and a shift in the load’s balance caused the truck to overturn, California Highway Patrol Officer Hector Placencia said.

“Fortunately, it’s not a flammable chemical so we’re just trying to contain the scene right now,” he said.

Due to the spill, which apparently involved antifreeze, officials were forced to issue a Sig Alert and close all southbound lanes of the 710 Freeway.

Traffic was being diverted to the southbound 5 Freeway, according to the CHP.

The southbound freeway remained closed for several hours before it reopened about 12:30 p.m., according to the CHP.
