Squad (7), Engine (3), and Traffic 33 were sent with Sq31 and R45 to I81 SB MM52.4 for a reported Tractor Trailer Overturned. Units made access NB in SB lane from the crossover and found one tractor trailer off the road into several trees with massive damage. C33 made access to the truck finding the driver conscious, answering questions, and miraculously not trapped. The cab was completely off the frame and facing back toward the truck. The trailer was torn open and most all of the contents were strewn through the wreckage and immediate scene. The crew from the Squad and Engine gained more access with saws cutting saplings and the perimeter fencing. Crews used a little giant ladder to assist the driver up and over the truck cab, which the roof was torn off. He was packaged and secured in the stokes baskets and carried to the hard road. Crews remained on scene until released by the Towing Company. Fire Police from 33 and 31 are still on scene as of 02:30 assisting until Penn DoT arrives. One lane is being maintained Southbound. This driver is very, very lucky based on the extreme damage from the impact of several large trees.
