Water bridges are bridge-like structures that carry channels waterways on other rivers, valleys, railways or roads Small ships and boats ply these rivers The bridge of the most popular water is the water bridge Magdeburg in Germany, the longest and most impressive in the world Although aqueducts was used to supply cities with water for centuries, they were not generally used for traffic until the 17th century when modern canal systems began to appear along the aqueduct to 662 meters with the Briare canal on the Loire was built in 1896 and remained the world's longest navigable aqueduct until the 21st century, when water bridge Magdeburg in Germany won the title.
Here are three of the most unusual and beautiful water bridges worldwide.
The Water Bridge Magdeburg in Germany deserve special mention Opened in October 2003 and a portion of the passage Magdeburg waterways, connects the Elbe-Havel Canal at Plateau, crossing the Elbe to 918 meters, it is the longest navigable aqueduct in the world.
The channels Elbe Havel Canal and Mittelland Canal had already met near Magdeburg but on opposite sides of the Elbe, which was at an altitude much lower than the two channels ships moving between the two had to make a detour of 12 km, Plateau down Canal by boat lift Rothensee in the Elbe, then sailing downstream on the river, before ascending to the Elbe-Havel Canal lock Niegripp by low water levels in the Elbe often prevented fully loaded barges to make this crossing, which requires a lot of time off -Loading cargo.
The reunification of Germany and the establishment of major water transport routes made the bridge a new water priority Work began in 1997, with construction taking six years and cost 500 million Bridge water now links the port system within Berlin with ports along the Rhine.
The Pontcysyllte Aqueduct, Wrexham County Borough in Britain, was built between 1795 and 1805 to carry the Ellesmere Canal over the River Dee valley to link Denbighshire coal mine to the national canal system during the industrial revolution This was one of the greatest technical achievements in the world of the time for over 200 years, it is the longest and highest aqueduct in Britain, and now a world Heritage site.
The aqueduct is 307 meters long, 3 4 meters wide and 1 meter deep 60, and forms part of a 18km long water system It consists of a cast iron tub supported 38 meters above the river on iron arch ribs made nineteen hollow masonry cells use both the distribution and wrought iron in the aqueduct enabled the construction of arches that were light and resistant, producing an overall effect that is both monumental and elegant.
The economic influence of the channel for the region has been considerable during the first half of the 19th century, enabling the rapid development of coal mining, metalworking, limestone quarries and lime production the slate quarries in the mountains of Wales and agriculture also benefited channel Today, the channel moves higher shipments of coal and limestone, but is a popular spot for tourists since 1954, the channel was managed and maintained in a seaworthy condition by British waterways.
Barton Swing Aqueduct is a mobile water bridge in Barton on Irwell in Greater Manchester, England, bringing the Bridgewater Canal across the Manchester Ship Canal The oscillating action allows large ships using the Manchester Ship Canal to pass underneath and small narrow boats to cross when the top of large ships must pass along the canal cruise, the 1,450 tons and 100 meters long hollow iron is set to 90 degrees in a door at each end of the tank holds about 800 tons of water; other doors on each side to hold water in their adjacent sections of the channel A similar turntable, but for road traffic, is adjacent to, and upstream of, the aqueduct Barton oscillation.
The aqueduct, which is the first and only swing aqueduct in the world is considered a feat of Victorian engineering Designed by Sir Edward Leader Williams and built by Andrew Handyside of Derby, the swing bridge opened in 1894 and remains in regular use.
Previously, the passage of the aqueduct over the River Irwell is a rigid stone structure that prevents new vessels of larger size to pass under the bridge A swing bridge has become a necessity.

Other notable water bridges, which are not included in this list are Top3 Avon Aqueduct - the longest and highest aqueduct in Scotland channel and the second longest in the UK, after the aqueduct Pontcysyllte and the Briare aqueduct that was the longest navigable aqueduct the world until the opening of the water bridge Magdeburg If you are interested, look on Google If you visit the United Kingdom, spare a day to visit these remarkable achievements in civil engineering.
