At 918 meters, it is the longest navigable aqueduct in the world.tvb now,tvbnow,bttvb- N. i5 H, H1 ^1 M. n1 C; o
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. & a8 T( b3 M, l) }- \' M

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. T9 p! z+ R6 O& G& c2 T, U, G2 w2 _, r5 Z: E1 f
