An overturned dump truck on the elevated Interstate 10 shut down the roadway near downtown New Orleans on Thursday afternoon, causing a miles-long traffic jam that continued well into the evening. It reached nearly into Jefferson Parish.

The accident was first reported about 12:30 p.m. on I-10 eastbound between the Canal Street on-ramp and the Orleans Avenue exit, said Capt. Edwin Holmes, a New Orleans Fire Department spokesman.

The NOFD classified the crash as a level-one hazardous materials incident since about 100 gallons of diesel fuel spilled from the truck.

The truck’s load of dirt was partially spilled onto the highway when it crashed into the concrete barrier that divides the east and westbound lanes, Holmes said.

The NOFD could not immediately say when the crash site might be cleared.

A Police Department spokesman said late Thursday evening that one eastbound lane on I-10 at Orleans remained closed due to the accident.

The NOPD was managing the traffic flow, but officials urged drivers to seek alternate routes if possible and expect delays.
