A tanker truck exploded late Tuesday afternoon on Interstate 10 in New Orleans East, causing a fire that destroyed the truck.

The heavily traveled highway had to be closed in both directions during rush hour, and a plume of black smoke was visible for miles.

The truck’s 24-year-old driver was taken to a hospital, but she was not seriously injured, police said.

The explosion happened about 4:30 p.m. on I-10 eastbound near the Little Woods exit.

The westbound lanes of I-10 were reopened about 6:30 p.m., although the eastbound lanes remained closed.

The New Orleans Fire Department’s hazmat unit was on the scene to clean up the wreckage.

Westbound traffic was diverted off the interstate at the Michoud Boulevard exit, and eastbound traffic was redirected at the Lake Forest-Chalmette exit.

The truck was carrying 8,600 gallons of gasoline when it overturned while merging onto I-10 from Interstate 510.

The cause of the explosion remained under investigation Tuesday night.
