At 918 meters, it is the longest navigable aqueduct in the world. / g' r6 |5 ^% q' [The 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. 2 x v# J$ G/ s1 ctvb now,tvbnow,bttvb6 H R8 c4 w8 D5 L8 W- M0 I0 D
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. , d" k0 @+ D2 x) ?( h5 [
