Rhône–Rhine Canal

The Canal du Rhône au Rhin is one of the important watershed canals of the French waterways, connecting the Rhine to the Saône and the Rhône and thereby the North Sea and the Mediterranean. As built, the canal was made up of four distinct sections:
Developments for high-capacity navigation in the second half of the 20th century thoroughly transformed this Y-shaped system. When the first lock was built on the Grand Canal d'Alsace at Kembs, a new cut was also excavated from Kembs to Niffer, and the rest of the Canal de Huningue was upgraded from here to the docks at Mulhouse. A 3-km-long section of the former Canal de Huningue, from Niffer to Kembs, is maintained and gives access to a boat harbour, while the remainder of that canal to Basel has been closed, and the terminal basin transformed into a whitewater canoeing course.
