CUMBERLAND COUNTY, Tenn. -- At least three people are dead after a crash and explosion on Interstate 40 in Cumberland County.

The collision happened at the Crossville exit, mile marker 320, and was reported a little before 3 p.m. Eastern time, according to TDOT Smartway.

Traffic is now being rerouted. Wreckers also were on the scene to remove impacted vehicles.

According to the Tennessee Highway Patrol, a tractor-tractor with no trailer was traveling east on I-40 when it crossed the median and hit a tractor-trailer hauling automobiles and a passenger vehicle.

Both rigs caught fire, and the drivers of both of them were killed. The driver of the other vehicle involved was also killed. A passenger in that vehicle was injured and transported by Lifestar to UT Medical Center.

Both a TDOT spokesperson and witnesses on the scene reported there were multiple explosions after the accident, and a large fire sent a huge plume of black smoke into the air.

The westbound lanes of I-40 remain shut down and will likely remain that way for a while. Traffic is being diverted.

Crossville police and city of Crossville personnel were working at the scene.

Viewer photos and videos from the scene showed heavy flames coming from what appeared to be wreckage from a semi-truck.

Kristopher Cole shared his Facebook Live of the scene with 10News in Knoxville. He said the truck had "exploded like 4 times"
