Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded5 u" U% _0 W3 y: s5 V- v H! ^8 J- u 公仔箱論壇1 ?- i& F. K* v) h& I

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. / _7 A/ L$ ~$ Ltvb 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. 公仔箱論壇 u1 o# s$ {' z3 X( M0 V

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. - f! V- u) q/ B' a: I/ a& Jtvb now,tvbnow,bttvbtvb now,tvbnow,bttvb. G" X" e3 x9 I
