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.
Dortmund–Ems Canal The Dortmund–Ems Canal is a 269 km long canal in Germany between the inland port of the city of Dortmund ( ) and the sea port of Emden. The artificial southern part of the canal ends after 215 km at Herbrum lock near Meppen. The route then takes the river Ems for 45 km to Oldersum lock. From there, the canal continues along a second artificial segment of 98 km . This latter section was built because inland ships at the time of the construction of the canal were not built for the open sea, which they would have faced at the Dollart and the entry to the sea port of Emden. It is connected to the Ems-Jade Canal from Emden to Wilhelmshaven.
