The Magdeburg Water Bridge is a navigable aqueduct in Germany that connects the Elbe-Havel Canal to the Mittelland Canal and allows ships to cross over the Elbe River. At 918 meters, it is the longest navigable aqueduct in the world. - v; W: o+ H5 Z/ j1 s5.39.217.77:8898The 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. + I; l( k$ a+ i7 N公仔箱論壇TVBNOW 含有熱門話題,最新最快電視,軟體,遊戲,電影,動漫及日常生活及興趣交流等資訊。* }1 _% o8 h& @/ g y" u
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. 8 \1 K3 T; e( Q2 w7 w8 w6 E $ C/ {1 i2 E+ i m" o w" G2 \4 Ntvb now,tvbnow,bttvb2 t8 V/ e. g' [5 W [attach]1486500[/attach] ! k2 y1 i% `9 a6 ]6 _TVBNOW 含有熱門話題,最新最快電視,軟體,遊戲,電影,動漫及日常生活及興趣交流等資訊。[attach]1486501[/attach] ( X; b; S5 j# r5 M' z1 X) Rtvb now,tvbnow,bttvb[attach]1486502[/attach] ; ]; G' E- V6 w# a4 sTVBNOW 含有熱門話題,最新最快電視,軟體,遊戲,電影,動漫及日常生活及興趣交流等資訊。[attach]1486503[/attach]5.39.217.77:8898: z) O' @/ l!
