It only needs to be designed to withstand the weight of the water! ) l f1 n# |# f! f: S; `5 G
Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loadedTVBNOW 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。& R1 V, {5 H# H# \ : u& h" F5 U) i6 Z$ z, _4 m5.39.217.77:8898 # U N3 \/ m2 D: Q/ a5.39.217.77:8898The Incredible Magdeburg Water Bridge in Germany L; Q2 o.

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.* E/ h0 ] ^8 T6 _' J& C) \1 @/ l/ 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. , }6 ?/ }0 @; I$ e0 Ytvb now,tvbnow,bttvbtvb now,tvbnow,bttvb: @: B3 d- _, H' [# b/ a6 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. , Y8 ~% U( m( E, v5.39.217.77:8898: a6 }- R: U2 M( B
