One person died and Interstate 10 was closed in both directions for hours Wednesday evening after three passenger vehicles and two 18-wheelers went up in flames from a crash at LA 415, said Trooper First Class Bryan Lee, a Louisiana State Police spokesman.

Work continued into the night to clear the crash scene. All lanes in both directions had reopened by 11:30 p.m., nearly six hours after the crash. Congestion finally cleared shortly before 1 a.m. Thursday, according to the Department of Transportation.

On Thursday morning, one lane on I-10 eastbound was blocked for debris removal. All lanes were cleared shortly after 7:30 a.m.

A person in a passenger vehicle died and six other people were treated with minor to moderate injuries from the crash, which occurred just after 5:30 p.m. Wednesday in West Baton Rouge Parish near the Lobdell exit, Lee said.

Much of the interstate was expected to remain closed through the night as the investigation and removal of the vehicles continued.

"Everybody's working right now to make sure that we keep traffic flowing and that we are able to get the roadways back open," Lee said.

More information on the cause of the crash was expected to be released Thursday morning.
