Canal de l'Aisne à la Marne

The Canal de l’Aisne à la Marne (French pronunciation: [kanal də lɛn a la maʁn], literally Canal of the Aisne to the Marne) is a canal in northeastern France which connects the Aisne and the Marne valleys. It runs from the Canal latéral à l'Aisne at Berry-au-Bac to Condé-sur-Marne on the Canal latéral à la Marne, a distance of 58 km. The canal rises 40m through 16 locks via the cathedral city of Reims, which is also a busy commercial port, to a summit level at an altitude of 95.70m. After crossing the watershed through a tunnel 2302m long at Mont-de-Billy, the canal drops down 23.80m through a flight of 8 locks towards the Marne.
