Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loadedtvb now,tvbnow,bttvb' k% q; g: |) Q& k 公仔箱論壇% W# U1 p- ~% `+ H

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. , R2 W# ?+ J b1 D) X$ Jtvb now,tvbnow,bttvbThe 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. ( J+ i6 L.

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. 公仔箱論壇! ~/ p! Q( s( t( ~4 g- M, D
