The eastbound 10 Freeway in Pomona reopened Tuesday morning after two crashes involving at least nine vehicles killed one person.
All lanes were reopened at North Towne Avenue about 6:30 a.m., California Highway Patrol logs showed.
In the hours leading up to Tuesday’s morning commute, only the left shoulder was open as crews worked to clean up the remains of Monday night’s fiery wreck.
All eastbound lanes had been temporarily shut after the accident, which authorities said occurred about 8:10 p.m. and involved a big rig and four vehicles in one crash and a separate accident involving four vehicles about the same time.
It was not immediately clear which incident was first, officials said.
Four of the victims were taken by two helicopters to local hospitals, according to the Los Angeles County Fire Department. An additional five suffered minor to moderate injuries, said CHP Officer Francisco Villalobos.
The big rig was loaded with furniture and spilled about 100 gallons of diesel fuel on the busy freeway.
One of the cars was trapped under the big rig and exploded in flames, the CHP said. In television news images, flames could be seen shooting out the back of the big rig.
One witness told The Times the truck was on the right side of the road, burning, and that occasionally an explosion could be heard.
The crashes remain under investigation.
