; V3 q/ f) R! G4 eos.tvboxnow.comThe Incredible Magdeburg Water Bridge in Germany 9 p/ y) t" B+ Los.tvboxnow.comThe 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.公仔箱論壇/ P- A; G9 m4 @% ^: m
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. ) S+ o" T8 S3 O- }% }os.tvboxnow.comos.tvboxnow.com# D1 G& Y$ C) p" w
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. * U; v, C1 X3 P3 e公仔箱論壇 ) P5 u6 u$ G( h$ g公仔箱論壇5 |6 c: Q5 |, r. Q/ Y1 n [attach]1486500[/attach] 7 o8 A) k( {.
