The Incredible Magdeburg Water Bridge in Germany
, m( E3 Z9 U3 G( D0 h6 rThe 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.
( i; t! A/ i* V/ q4 J2 G& w. ~5 ~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. ) g p; Y; F, E2 U! X6 P# I

The aqueduct was finally completed and opened to the public in 2003. , N, v2 u2 k O- }, |" l" [
