The Incredible Magdeburg Water Bridge in Germany
, Q; z; u2 P( S+ i$ w9 ~+ Y2 Z' ^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。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.tvb now,tvbnow,bttvb, U% {6 a! h4 z7 i6 ]
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.
