At 918 meters, it is the longest navigable aqueduct in the world. * O+ y0 z7 r8 [0 U公仔箱論壇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. 0 t- v" `2 b) P) ?* c& Mwww.tvboxnow.com # k* |$ j$ t- |3 d- o!
