A tractor-trailer caught on fire Monday night near the top of the Ridge Cut, causing a major blockage of traffic going toward Brainerd.
Traffic was being routed off of I-24 eastbound at Rossville Boulevard.
The wreck happened around 7 p.m.
Left lanes were later opened, but the right lanes were not expected to be cleared until around 2 a.m.
It was reportedly a Fed-Ex truck involved with one of the trailers carrying ammunition.
The truck was on its side and split apart with heavy damage.
