UPDATE 3:13 p.m.

Hazmat technicians are in the process of offloading sulfuric acid from a tanker truck that caught fire on the northbound side of the Causeway Thursday morning, a spokesman for State Police Troop L said.

The process takes about 20 minutes, Trooper Dustin Dwight said.

One lane remains closed on the northbound side. WWL-TV reports that all lanes were briefly closed while the truck that will take the acid away was put in position.

UPDATE 11:30 a.m.

Southbound lanes and one of the three northbound lanes on North Causeway Approach are being reopened after firefighters extinguished the fire on the tanker truck, Mandeville Police Chief Gerald Sticker said.

The truck was carrying sulfuric acid, but no chemical escaped, Sticker said. He anticipates that northbound lanes will be closed again when another trailer is brought in to offload the chemicals.

Sticker said to expect traffic delays.

The truck was the about to exit the northbound Causeway when the rear began smoking, Sticker said.

A Homeland Security agent, who was behind the truck, saw that it was catching fire and was able to alert the driver, who was unaware.

The truck stopped at Brookside Drive, and both the agent and driver tried to put out the fire with extinguishers to no avail.

First responders from St. Tammany Fire Protection District No. 4 arrived and were able to get the blaze under control  before the tanker was compromised, he said.

UPDATE, 11 a.m.

The fire has since been stifled and the truck's tank was not breached, according to WWL-TV's Ashley Rodrigue

Individual lanes in both direction were opened about 11 a.m.

The fire originated in the braking system of the trailer, according to the report.
