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. " X7 q, Y# M6 G1 M6 T# X5.39.217.77:8898The 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. tvb now,tvbnow,bttvb4 t3 |' q: c- O' ^% ]8 V2 [

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. 6 o0 c" J" R \( p- g- utvb now,tvbnow,bttvb . `$ K' _9 l" k% N8 h8 q5.39.217.77:8898tvb now,tvbnow,bttvb& A0 t; Y3 Z. `: v$ z!
