One person has died after a fiery crash involving multiple tractor-trailers that closed part of Interstate 91 south in Windsor on Tuesday morning.
Two tractor-trailers were involved in the crash near exit 39 before they caught on fire shortly before 1 a.m., state police said.
One person has died. His or her identity has not been released, according to authorities. Video from the scene shows flames shooting out of the back of one tractor-trailer and thick gray smoke.
Dozens of first responders worked to extinguish the blaze.
Fire officials said they used firefighting foam containing the potentially hazardous chemical PFAS to put it out. It took about an hour and a half because the fire was so deep seeded.
Firefighters said they did everything they could to keep the firefighting foam from getting into any waterways.
