Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded1 Z8 s4 a6 }( }/ ^6 k& j: M 4 ^# h# \5 w3 w1 j+ {- P) X( ~! ]2 K( |+ a) G# w/ K1 u The Incredible Magdeburg Water Bridge in Germany 4 v& P, {, ~1 l3 bTVBNOW 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。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.5.39.217.77:8898" H* @2 ^% ~5 K
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. ' r& H# h' x0 etvb now,tvbnow,bttvb( p( I1 p+ d* K3 e
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. 3 R; d8 X" B. A: p" M- i+ s公仔箱論壇 " G% r1 N9 h.
