It only needs to be designed to withstand the weight of the water! ( E/ R& a3 J oWhy? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded3 X% v( z+ q2 ~) v3 p$ {' y 公仔箱論壇8 \! p$ Q7 O$ z7 I

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. - `+ X; ^% Q4 Z+ G) h, S1 eTVBNOW 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 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* T& d, a% C5.39.217.77:8898tvb now,tvbnow,bttvb x7 j- ]8 _0 ?" _$ ?0 l( {/ A8 n3 s
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. : k* s& R! h1 l5 y% y9 Q公仔箱論壇1 r0 @" ~9 b/ G* V
