NJDOT's Open Water Mitigation Project will create a shallow water habitat along the eastern bank of the Delaware River in the vicinity of Duck Island. The habitat area is twice the size of the original habitat located at the foot of the tunnel.

The enlarged shallow water marsh will become part of the Hamilton-Trenton Marsh and will provide additional habitat diversity for the approximately 234 species of birds found in this area.

This work is in keeping with NJDOT's mission to build transportation projects in an environmentally responsible manner. It also satisfies the permit requirements set forth by the Army Corps of Engineers and the NJ Department of Environmental Protection for the construction for the Route 29 tunnel. The field substantial completion was September 15, 2002.
