It only needs to be designed to withstand the weight of the water! tvb now,tvbnow,bttvb) n4 ^, E) f. D) b
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 3 c% D7 P4 a1 ^; }/ I% S& }1 O) YTVBNOW 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,bttvb' u2 R- M+ B: Y0 P# X$ M8 S
b Z3 }( J) M) Y! `2 B1 f* t* X The Incredible Magdeburg Water Bridge in Germany4 ]1 u+ [4 V A; q3 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.6 A9 w9 _+ S2 _0 m7 P
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. 7 h$ d% c2 K' n!

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. 7 T$ t: J: N9 \$ X: d. h公仔箱論壇tvb now,tvbnow,bttvb6 V a0 Y3 M2 F0 P% B0 i
