The Cape May Canal is a 2.9 nautical miles (3.3 mi; 5.4 km) waterway connecting Cape May Harbor to the Delaware Bay, at the southern tip of Cape May County, New Jersey. There is a long history of unfulfilled plans for a canal across Cape May. The canal was finally constructed by the United States Army Corps of Engineers during World War II to provide a protected route to avoid German U-boats operating off Cape May Point and to become part of the Intracoastal Waterway.
