Which Canal was constructed during World War II, Middlesex Canal or Cape May Canal?
Cape May Canal The Cape May Canal is a 2.9-nautical mile (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. The canal was dredged as a wartime emergency measure in 1942 and was the final link in a protected waterway intended to allow coastal shipping to travel along the coast with a greatly reduced risk of attack from German submarines.
