1) car crash was unusually explosive, engine thrown 30 yards from car.
2) from the videos it appears the accident was not directly on the interstate but near a parallel access road.
**** Hwy #16 is a federal road and the only road to some of the Islands...very old road I think was was Mr Herman Talmadge who had it built.
If anything it was speed they drive 150mph on those roads.
thanks for the info, was curious about the road.
