The most prominent water bridges of peace
Water bridges are similar to conventional bridges, with the difference that they are navigable canals and waterways on the rivers, valleys, railroads or highways. Small ships, boats and ferries on these channels, thereby substantially reducing its way.
Has long aqueducts were used to supply water to the city and to the 17th century, no one thought to use them also for vessel traffic. With the advent of modern canal systems began to appear and the relevant aqueducts, for example, the channel on the river Loire, built in 1896. It was he who remained the longest navigable aqueduct to the world of the 21st century, when the Magdeburg Water Bridge in Germany was built.
1. The Magdeburg Water Bridge
The bridge was opened in October 2003 and connects channels Elbe-Havel with Mitteland, crossing the river Elbe. C in 918 meters - the longest navigable aqueduct in the world.
Previously channels Elbe-Havel and Mitteland met in Magdeburg, but on opposite sides of the Elbe River, which flowed significantly lower than the channels themselves. To move from one channel to the other ships had to make a detour of 12 kilometers, then spend an hour on the descent in a special elevator for boats to Elba, and then rise again to another channel, located above. On top, low water level in the Elbe often prevented fully loaded barges passing through the channel successfully done this intersection. I had to spend quite a lot of time for loading and unloading goods. After the reunification of Germany and the establishment of major trade routes of the country building water bridge was the number one priority for the government.
Work began in 1997 and construction took 6 years and cost 500 million euros. Water Bridge connects the internal network of the German channel with ports along the Rhine River.
2. Pontcysyllte Aqueduct
Pontcysyllte Aqueduct is located in Rekskheme, UK .. It was built between 1795 and 1805 year to bring the Ellesmere Canal over the valley of the River Dee. The main purpose of the construction was to link coal mines Denbighshire with the national system of canals during the Industrial Revolution, when the country's economy is developing rapidly. Construction has become one of the greatest technical achievements of its time. For the past 200 years Pontkisillte is the longest and highest aqueduct in Britain, and is now a UNESCO World Heritage Site.
Aqueduct length is 307 meters, width - 3.4 meters, and the depth is 1.60 m. Pontkisillte part aqueduct 18 kilometers in length and is made of cast iron, supported iron curved ribs strength at a height of 38 meters above the river. The ribs 19 abut the huge piers of masonry. The use of such materials as stone and iron are allowed to create the arch, looking easily and elegantly and at the same time having a very high strength.
The economic impact of the channel on the development of the whole area was just huge, especially in the first half of the 19th century. Increased extraction of coal, ore, limestone and production of lime. Slate career of Welsh mountains and agriculture also learned considerable benefit from the construction of the channel. Today it is no longer moving barges with coal and ore - aqueduct has become a popular tourist attraction. Since 1954 channel operate and maintain its experts from British Waterways.
3. Barton aqueduct Swing
Barton Swing Aqueduct - a mobile water bridge in Barton that in Greater Manchester, England. He carries the Bridgewater Canal, crossing the Manchester Ship Canal. Its special device makes it possible to translate as small tour boats and large ships. This is the first and only moving the aqueduct in the world, which is considered a major feat of Victorian civil engineering.
Designed by Sir Edward Williams and built by Andrew Handyside, a mobile aqueduct opened in 1894 and is still in regular use to this day. Previously, there was located a stone aqueduct, which did not allow large ships to cross the river Irwell. Thus, Barton Swing was the only one solution to this problem. Another outstanding structure is the water wheel of Falkirk - a huge lift for boats.
In the photo below you can see the Swing Aqueduct in the closed position (left), as well as the Bridgewater Canal, crossing the navigation channel. Barton Road Swing Bridge is located on the right:
Other notable water bridges are not included in this list of the top 3, you can select the Avon Aqueduct - the longest and highest in Scotland. It is also possible to add a selection of Briard aqueduct, which is included in the list of the most prominent attractions of the UK. He was the longest navigable aqueduct in the world before the opening of Magdeburg Water Bridge. As you know, most of these facilities located in the UK, so if you want to see all these wonders, will have to spend a lot of time, but eventually you will get a lot of positive impressions.
