Construction of the Mittelland Canal was started in 1906, starting from Bergeshövede (municipality Hörstel) on the Dortmund-Ems Canal. The section to Minden on the Weser was opened in February 1915 and was initially named "Ems-Weser-Kanal". The section from Minden to Hanover was finished in the autumn of 1916. The section to Sehnde and the branch canal to Hildesheim were completed in 1928, Peine was reached in 1929, and Braunschweig in 1933. The final section to Magdeburg was opened in 1938, thus creating a direct link between Western and Eastern Germany. The branch canal to Salzgitter was opened in 1941. The planned canal bridge over the Elbe, necessary to avoid low water conditions in summer, was not built due to the Second World War.
