TARRYTOWN - It was a traffic nightmare for drivers heading over the Tappan Zee Bridge toward Rockland County early this morning.

Cars and trucks were at a dead stop on the northbound side of the bridge for a couple hours overnight. The problems started when a truck hauling scrap or sheet metal began spilling debris that went all the way into New Jersey before the driver was stopped.

Some cars suffered damage when they hit the debris adding to the problems. It took until 6 a.m. to clear the metal from the roadway.

The new Tappan Zee bridge is actually designed to prevent these kind of traffic problems from happening, officials say. Because the new span will actually be two bridges, traffic could be diverted to one side, however it will be years before the new bridge is finished.
