The canal was built in two phases, the second much longer than the first. King
Louis XIV's ministers
Colbert and Mazarin had both proposed linking the rivers
Oise and
Somme in the 17th century and this resulted in the
Canal Crozat, or
Canal de Picardie, between
Chauny and
Saint-Simon in 1738. The remainder, connecting the Seine Basin with the
Escaut was a lengthy process. The original designer, Devicq in 1727, died in 1742. Little was accomplished until
Napoleon demanded that work begin again in 1801. He officiated at the opening in April 1810. The canal was such a success that the locks had to be duplicated throughout in the early 20th century, at the same time deepening the channel, enlarging the tunnels, and increasing water supplies. Later improvements included electric barge traction on rails, installed during
World War I, mechanising locks, and providing public lighting on the busiest sections. Later, the locks were equipped for automatic operation, using remote sensors, and more recently, using handheld remote control. By 1878, up to 110 barges were crossing the summit level daily. The
Canal du Nord was built as a duplicate route and completed in 1965. The canal carried more freight than any other man-made waterway in France in 1964.

Hindenburg Line, a German defensive position built during the winter of 1916–1917. The Allied
crossing of the St Quentin Canal in 1918 was a significant part of the
Hundred Days Offensive that led to
the Armistice. == Navigation ==
