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.
Nutbrook Canal The Nutbrook Canal was a canal in England which ran between Shipley in Derbyshire and the Erewash Canal, joining it near Trowell. It was built to serve the collieries at Shipley and West Hallam, and was completed in 1796. It was initially profitable, but from 1846 faced competition from the railways, and more seriously, subsidence caused by the coal mines that it was built to serve. With the mines failing to pay tolls for goods carried on the canal, and in some cases refusing to accept responsibility for the subsidence, most of it was closed in 1895, although the final 1.5 mi remained in use until 1949.
