The accident happened during the evening rush Wednesday near the intersection of Route 70.
The man, who was not a Manchester resident, was alone in his vehicle.
The mayor says it is a very busy intersection, especially during the rush hour.
The man has not been identified pending family notification.
"It came down like hell, I'll tell you, it was like a bomb explosion went off," said Herman Kapiloff, a Manchester Township resident.
Herman Kapiloff and his wife Rita were inside their house when it suddenly got dark and the hail began to fall, and so did trees all around them.
Rita went out to see how bad it was and that's when the tree that hit their house shifted.
"All of a sudden I saw it move and come towards me," Rita Kapiloff said.
It hit her in the face and cut her lip, but she's going to be OK.
