Once the old Tappan Zee Bridge is blasted to bits Tuesday, its larger bits will live underwater.

Debris from the bridge is being added to six man-made reefs off the coast of Long Island.

Diver Elliot Bertoni has explored some of those artificial reefs. They contain things like old ships and other items.

"The fish want a habitat to survive in and it allows the smaller fish from being prey for the larger fish," says Bertoni. "It's a neat world, its a different world."

The reefs also provide a boost for the fishing and spots diving industry.
