The 14 Freeway is expected to be partially closed for hours in the Acton area on Tuesday after a propane truck overturned following a collision involving a camper and another car, authorities said.
The multivehicle crash occurred on the southbound 14 at Crown Valley Road just before 9:15 a.m., according to the California Highway Patrol’s incident log.
Five injured people had to be extricated from the camper — which also overturned in the wreck — and four were taken to hospitals, a tweet from the Los Angeles County Fire Department stated.
A mother and child were among four passengers who were critically injured, the L.A. Times reported.
The tanker truck was carrying some 2,600 gallon of propane, some of which spilled onto the roadway, fire officials said.
A perimeter of roughly 500 feet was established as crews worked to slow the leak from the truck and shut the valve. A hazardous materials team has been called to the scene.
Multiple businesses in the area have been evacuated, according to the Fire Department.
CHP issued a SigAlert around 9:50 a.m. as it shut down all southbound lanes at Crown Valley Road, along with that on-ramp.
One lane has since reopened, but the other closures were expected to be in place for about four hours, the agency said.
The cause of the crash is under investigation.
