- Blyth Navigation
The Blyth Navigation was a
canal inSuffolk ,England , running seven miles (11 km) fromHalesworth to theNorth Sea .Following an
Act of Parliament , which was passed on 1 April 1757, [ [http://www.jim-shead.com/waterways/sdoc.php?wpage=PNRC0079#PNRC078 Joseph Priestley, (1831), "Historical Account of the Navigable Rivers, Canals, and Railways, of Great Britain"] ] its construction was completed in 1761 at a cost of £3,000. It initially had four locks; a fifth was added later. From the sea, the Navigation follows the River Blyth until it reaches theTown River , which it follows toHalesworth Lock. From here, the New Cut took the canal to a wharf at Halesworth, which formed the terminus of the canal. The New Cut joined back up with the Town River a little further to the west, in order to provide the water supply for the locks.In order to allow wherries to reach his maltings, a local maltster named Patrick Stead increased the water levels above the point where the New Cut and the Town River joined, by building an additional lock near the junction.

The locks were constructed to allow wherries to use the navigation, and so were 50 ft long and convert|14|ft|m|abbr=on wide (15.2 x 4.3m). However, they were unusual, in that the side walls curved outwards in the centre, to provide an extra 1.5 ft (0.45m) of width.
Navigation ceased in 1934. Some efforts have been made since to restore it, but the resultant flooding of bordering land has made this unpopular.
