At 918 meters, it is the longest navigable aqueduct in the world.tvb now,tvbnow,bttvb, U% {6 a! h4 z7 i6 ]
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. ; y3 n+ P4 z7 P( n! y , m" _3 ~+ j2 E6 Stvb now,tvbnow,bttvbConstruction 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.
