About the project
This development scheme involves dredging as needed within the existing 40-foot Delaware River federal navigation channel to deepen it to 45 feet from Philadelphia Harbor, Pa. and Beckett Street Terminal, Camden, N.J. along a 102.5-mile distance to deepwater in the Delaware Bay.
The deeper channel will provide for more efficient transportation of containerized, dry bulk and liquid bulk (crude oil and petroleum products) cargo to and from the Delaware River ports, with estimated net annualized benefits of more than $13 million to the U.S. economy.
Under a Project Partnership Agreement signed in 2008, the total cost of initial construction, approximately $300 million, is shared 35 percent by the Philadelphia Regional Port Authority as the non-federal sponsor, and 65 percent by the federal government through the U.S. Army Corps of Engineers.
