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) A$ n: t# {: ^& g) D3 x 9 P& v& K" T) h6 d! y$ ^

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; v4 e% g% }" @( E& t
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. . }. s5 z* g0 t. @9 @' ^www.tvboxnow.comwww.tvboxnow.com( A Z ^/ `, F' U
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. 6 w, q5 ]$ j, q/ @, i- ^ 5 g% P( F$ c8 L+ J9 Qtvb now,tvbnow,bttvb公仔箱論壇" y# e+ l) y) l [attach]1486500[/attach] 7 ?% O( I7 _- @6 o, K( d: x[attach]1486501[/attach], z' a4 c6 y# l1 q* q$ ^1 T [attach]1486502[/attach]tvb now,tvbnow,bttvb& O7 M0 n& `6 ?)
