Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded ( n! s# ]1 S, e0 c4 Y * w7 Q- t3 k2 t6 ctvb now,tvbnow,bttvb + C* o1 X0 D% K4 Q% [% P公仔箱論壇The Incredible Magdeburg Water Bridge in Germany' G2 A0 U! ^2 D' [! s& [- d& P
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.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。& V/ l) E/ J( `0 h6 b
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. ( B: @& p0 O4 Y5.39.217.77:8898- E5 w; h; p! H0 l
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. : x$ }0 l; T; \1 l7 F" {+ R6 \; o
