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 6 G* p6 K2 F; r, L5.39.217.76 0 ]4 ^- @9 M8 ~, l3 E8 }2 ]$ t) ^$ _1 C+ u( b( k The Incredible Magdeburg Water Bridge in Germany 2 E3 _$ Y$ W: X; p3 G7 V$ uTVBNOW 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. 7 j0 H3 o a, I4 itvb now,tvbnow,bttvbThe 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. & h8 e) b# h1 ]9 g0 Y7 X, UTVBNOW 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。 " V. s& h, b% w- l) D' X1 C9 D) {& B公仔箱論壇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.
