At 918 meters, it is the longest navigable aqueduct in the world. n5 n3 t4 u; i2 J$ N7 h5 e$ u9 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. , ? A7 o m0 _6 g' ^5.39.217.77:8898; h3 x) ]+ \! o
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. tvb now,tvbnow,bttvb4 ^7 w: D2 U4 M* @
