This morning While comming up I-81 there was a Traffic back up for about 10 miles in TN on I-81 at about mile marker 22 is where a Big Truck and its Trailer were burt completely to the Ground the only thing left of he tractor was the frame and engine the only thing left of the trailer was the frame and rear door suppots all the sides skins of the trailer was completey gone. Looked to be a complete loss. THe TN fire department had its Foam truck and a Pumper there. The truck was not overturned and was on a flat plane on the right hand side of the road. But Both Tractor and Trailer were in a melted mess. Like I said no Evidence of a Cab for the tractor and the Trailer side walls were completely gone.
