It only needs to be designed to withstand the weight of the water! ( N. y+ I3 g6 v/ `
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 e1 M3 J9 L: j# d5.39.217.77:8898* w3 d4 Q0 D/ h- [

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.TVBNOW 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。* Z1 x1 O1 A; u
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. + h6 T& T8 l* i% }5.39.217.77:8898 0 {4 K4 {- H5 j. o0 m( t2 Y1 u* {6 }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.
