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.
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.
