Water bridges structures are that carry navigable waterway canals over
other rivers, valleys, railways or roads. It is uncommon concept in the
world and this helps in small ships and boats ply on these waterways.
The most famous water bridge is the Magdeburg Water Bridge in Germany,
the longest and the most impressive in the world. The Magdeburg Water
Bridge is a navigable aqueduct in Germany that attaches the Elbe-Havel
Canal to the Mittelland Canal, and let ships
to cross over the Elbe River. At 918 meters, it is the longest
navigable aqueduct in the world. The Elbe-Havel and Mittelland canals
had in the past met near Magdeburg but on opposite sides of the Elbe.
Ships moving between the two had to make a 12 KM detour,
descending from the Mittelland Canal through the Rothensee boat lift
into the Elbe, and 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. The construction of the water link was begun in the early 1930s
but due to the World War II and subsequent division of Germany the
constructions remained suspended till 1997. The bridge
took six years to build at a heavy cost of about half a billion euros,
and will enable river barges to avoid a lengthy and sometimes unreliable
passage along the Elbe. The stunning aqueduct was finally completed and
opened for public in 2003.
