Which Canal was constructed during World War II, Middlesex Canal or Cape May Canal?
Middlesex Canal The Middlesex Canal was a 27-mile (44-kilometer) barge canal connecting the Merrimack River with the port of Boston. When operational it was 30 feet (9.1 m) wide, and 3 feet (0.9 m) deep, with 20 locks, each 80 feet (24 m) long and between 10 and 11 feet (3.0 and 3.4 m) wide. It also had 8 aqueducts.
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.
