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.
Capestang bridge The Capestang bridge over the Canal du Midi at PK 189 at Capestang is a very important structure for those wishing to motor on the canal. It is used as a measuring device as it is the lowest structure on the canal. A boat, with an air draft under 3.3 m at the center and assuming a beam no more than 5 m , a height of no more than 2.4 m at the extremities, should make it under the bridge. A British boat builder who builds boats for several of the boat hire companies in France builds their boats to meet these requirements.
