The man was struck in the northbound lanes and hurled onto the other side of the highway near the Ramsey Outdoor store around daybreak Dec. 8, they said.
He was pronounced dead at the scene a short time later.
There was no immediate word on the type of vehicle or vehicles that struck him or who was driving.
The incident was part of a chain reaction of events that shut down the busy highway into the morning rush.
Another involved a fiery stolen car crash in Saddle River that dropped lines across the road during a pursuit up Route 17.
