An 18-wheeler leaking a hazardous chemical between Rayne and Crowley prompted emergency officials to shut down Interstate 10 in both directions near Rayne around 6 p.m. on Monday, according to the State Police.

Master Trooper Brooks David said westbound motorists are being rerouted to exit I-10 in Lafayette, proceeding on Interstate 49 north to U.S. 190 West.

Eastbound travelers detoured at La. 1111, and proceeded to U.S. 90 in Rayne, police said.

David said the tanker spilled sodium hydrosulfide, a corrosive and toxic liquid.

“Interstate 10 is going to be shut down for an unknown amount of time,” David said. He said hazardous materials personnel probably will have to unload the tanker and transport the cargo elsewhere before State Police reopens I-10.

David said he did not know if the incident resulted in any injuries.
