It only needs to be designed to withstand the weight of the water! ~ @0 |2 F' l. W2 P/ g2 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 4 H7 a: k3 T5 y" l# T1 @0 p公仔箱論壇5 a; K2 h+ \- v5 p% @

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. # B0 ?6 z/ M3 r& r9 L. ?/ |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. 5.39.217.77:88989 B( Q- K9 m8 q* Q% ]/ |

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. 9 e X/ L0 b8 E0 o1 ?公仔箱論壇 " Q; n& J% a- P/ K5.39.217.77:8898- n9 q. _. k1 e5 k2 } [attach]1486500[/attach]5.39.217.77:8898* H, W9 c2 ^* s [attach]1486501[/attach]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。, w2 r# b.
