LENOX TOWNSHIP, SUSQUEHANNA COUNTY (WBRE/WYOU) Part of I-81 Southbound is shutdown after a Tractor Trailer fire.

The fire broke out just after 3 a.m. Wednesday near the rest area between the Lenox and Glenwood/Lenoxville Exits.

Officials tell Eyewitness News the big rig was hauling plastic products and that fighting the fire is challenging.

Heavy equipment was brought in to tear apart the products in the trailer to ensure the fire was put out properly.

No injuries were reported.

Both southbound lanes are closed and traffic is backed up. You should consider taking an alternate route.
