It only needs to be designed to withstand the weight of the water! tvb now,tvbnow,bttvb& N) b. s" A8 u% L
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 2 D! f0 b, q: G( A/ H公仔箱論壇 . t1 U( X" m4 z5 h$ S& a- W" R2 [) B公仔箱論壇5.39.217.77:8898; L7 l' P0 O+ q, s5 H( u% H0 y The Incredible Magdeburg Water Bridge in Germany% K6 f6 f# h2 [3 {) E: ^9 J w' W( 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.公仔箱論壇' Y' k* }! V6 r9 h
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. ! d4 @0 Q: s8 p; dtvb now,tvbnow,bttvb0 U3 l: J0 \% |8 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. 1 g! m5 m' k. h6 m, J# I9 c" _
