At 918 meters, it is the longest navigable aqueduct in the world. 9 I, Z" ]' e2 b V5 E7 qThe Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe Ships moving between the two had to make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo.

Construction of the water link was started as early as in the 1930s but due to the World War 2 and subsequent division of Germany the work remained suspended till 1997. The aqueduct was finally completed and opened to the public in 2003. 1 V3 k, D, ^2 @7 [公仔箱論壇tvb now,tvbnow,bttvb& C" K- C, J: Y# [: J9 L
