The Rhone–Rhine Canal is a significant waterway of France, that can be considered to connect the Rhine and the Rhone and thereby the North Sea and the Mediterranean. The canal was planned from 1784 onwards but finally originally opened in 1834, although the River Doubs which it incorporated has been significant since earliest times. Changes happened in 1960, with the opening of the enlarged Kembs-Niffer branch at the eastern end and the closure of part of the northern arm. A major project to substantially increase the size of the whole canal to accommodate Rhine-size commercial traffic was abandoned in 1997 and part of the allocated funds were used to modernise navigation on the canal.
