It only needs to be designed to withstand the weight of the water!
9 L9 u# T# j$ K2 S5.39.217.76Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded

The Incredible Magdeburg Water Bridge in Germany
' d/ D u2 u+ m; `" ?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。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.
3 }( O/ x7 O! d% M x2 y1 \& uThe 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.

The aqueduct was finally completed and opened to the public in 2003. + D& p; w! I) l/ t* V
