It only needs to be designed to withstand the weight of the water! ! F/ i8 M& _ g7 H
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 , y% Y O/ Z! s/ _3 ^# | D+ o/ ^; W0 q, I& p. xTVBNOW 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。 / D% z9 p; w( N+ u) h公仔箱論壇The Incredible Magdeburg Water Bridge in Germany/ A( }5 G/ j/ b: s( R7 P( g
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3 W/ f Z5 h9 v5 ]8 s
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. 1 \+ L7 @7 R" x0 O5 pTVBNOW 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。 # |& r. t1 R+ Z6 y% E }tvb now,tvbnow,bttvbConstruction 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.
