A big rig carrying sulfuric acid overturned on the eastbound 10 Freeway in Baldwin Park early Tuesday morning prompting an hourslong closure of several lanes, including the northbound 605 transition to the eastbound 10.
The crash was reported about 1:39 a.m. near Frazier Street, according to the California Highway Patrol’s traffic incident log.
It was unclear what caused the big rig to overturn, but the incident caused at least two other vehicles to become involved in the crash.
Simon Cohen said he was driving his Honda Odyssey when all of a sudden, he saw a “black wall.”
Cohen said he was then struck from behind and his vehicle was pushed into the big rig.
Officials are still investigating the details of the incident.
Cohen said a 55-year-old passenger in his vehicle was taken by ambulance to a local hospital with neck pain.
The driver in the second car was not hospitalized.
The big rig driver was taken to a hospital, but only as a precaution, an investigating officer at the scene said.
A hazmat team was called, although none of the sulfuric acid the big rig was carrying is believed to have spilled.
Officials want to make sure the acid is safe before attempting to upright the big rig.
A SigAlert was issued just after 2 a.m. for all but two lanes on the eastbound 10 Freeway and the entire transition road from the northbound 605 to the eastbound 10.
Officials had hoped to reopen the lanes by 6:30 a.m., but later revised that estimate after another crash was reported in the area.
The big rig was finally removed and all lanes were completely reopened just before 10 a.m., the CHP tweeted.
