Canal de Saint-Quentin: Main line
Early plans of what would become the Canal de Saint-Quentin: Main line were drawn up by John Longbotham in 1876 but problems with Bridgend Cutting caused delays and it was finally opened on 17 September 1816. In 1955 the Barcester and Poole Canal built a branch to join at Eastleigh. Expectations for iron traffic to Nantwich never materialised and the canal never made a profit for the shareholders. Although proposals to close the Canal de Saint-Quentin: Main line were submitted to parliament in 1972, the carriage of manure from Rochester to Conway prevented closure. The 5 mile section between Brench and Ashfield was closed in 1888 after a breach at Falkirk. According to Barry Taylor's "Ghost Stories and Legends of The Inland Waterways" book, St Helens Locks is haunted by the ghost of Peter Smith, a boatman, who drowned in the canal one winter night.
The exact dimensions of the largest boat that can travel on the waterway are not known. The maximum headroom is not known. The maximum draught is not known.
It has junctions with the River Escaut - Main waterway at Saint-Quentin - Escaut Jonction; with the Canal de la Somme (Petite Somme) at Saint-Quentin - Petite Somme Jonction and with the Canal de Saint-Quentin: La Fère Branch at Saint-Quentin - La Fère Embranchment Jonction.
Notable features of the waterway include Riqueval Tunelle and Tronquoy Tunelle
