It only needs to be designed to withstand the weight of the water! # R% k# i, R+ O7 c( |8 _7 N5.39.217.77:8898Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded 0 o* h( M5 b2 Y0 H% M* H5.39.217.77:88984 @3 l8 h' j9 P) b' V ~
! M, A) M( K! _ The Incredible Magdeburg Water Bridge in Germany ; X5 q$ Y- n$ U( q$ [: ?公仔箱論壇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.公仔箱論壇2 h/ [2 V# {* N
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. + N0 {& n$ V' b9 M6 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。 ; j+ n2 z4 V0 r8 ]7 Z# u! y, FConstruction 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.
