At 918 meters, it is the longest navigable aqueduct in the world. % ]& x$ q) S0 E1 S6 ftvb now,tvbnow,bttvbThe 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. $ O/ i, j/ C* F3 Mtvb now,tvbnow,bttvb5.39.217.77:8898" O% n4 u+ ^* k: [# q/ j- y
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. 5.39.217.77:88983 k% c9 o# l$ z0 D
