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 ( g3 q/ y/ b) T; I* m! y$ G4 ]3 s% b! ^ ; E. x$ Q1 X( @* K2 GTVBNOW 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。tvb now,tvbnow,bttvb6 x1 K& E# A3 i/ b) I3 g2 ^2 B* j The Incredible Magdeburg Water Bridge in GermanyTVBNOW 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。& y8 O x* F.

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.8 p7 {- q# z/ A Y
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.

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. # h! p3 d& `: m% N% p% Ntvb now,tvbnow,bttvb / V! f( j3 I- ~2 ^: d5 Q4 q+ i9 U5.39.217.76 : B' e6 O; g. }1 q( L[attach]1486500[/attach]5.39.217.763 [( f9 ?'
