It only needs to be designed to withstand the weight of the water! 公仔箱論壇8 [, r- T' Y4 @+ Z! X/ k
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 8 |/ e. k.

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.5.39.217.77:8898: d& N! s) V+ Z# b5 c3 k
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. 公仔箱論壇! {6 H; |- A5 w4 U/ W

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. 8 v0 J3 b- }2 Q1 d- [0 x 9 @% _' U) { J2 {6 x: E+ F + J( ]* }+ \- ?) n8 ^# e& Stvb now,tvbnow,bttvb[attach]1486500[/attach] + t; H: K( o7 i/ M; p* |& iTVBNOW 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。[attach]1486501[/attach]! x% o$ p# K. `( Z [attach]1486502[/attach]公仔箱論壇' p+ l8 x2 F3 \ ~" M [attach]1486503[/attach] !
