It only needs to be designed to withstand the weight of the water! A* {; s/ j5 Mtvb now,tvbnow,bttvbWhy? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded 8 N) C& a: Z- r7 x2 ~& @% Stvb now,tvbnow,bttvb' G8 _3 {0 Z; w) E

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. ' v' n: n- W' q, Q8 [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. 1 Z! E$ D# v7 Z: X3 c) A0 ltvb now,tvbnow,bttvb!

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. $ u4 S& ^( z4 T( TTVBNOW 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。 5 ?9 E% {+ N% N; Itvb now,tvbnow,bttvb / t+ r! |; h5 Ptvb now,tvbnow,bttvb[attach]1486500[/attach]!
