Bridge - is one of the most beautiful engineering structures, which connects the banks of rivers and lakes, seas and valleys.Without it seldom does a modern rail or road.Many bridges are symbols of cities and states, making gold fund of technical thought of this or that state.Many designers and engineers tend to ensure that their construction was included in the list of "most-most", doing this all their art and talent.One of the most prestigious is the title of "the longest bridge in the world."
For many thousands of years of human history, the title passed from one to another engineering construction, the builders putting new challenges.Today, the longest bridge in the world is in China.This is a huge viaduct, located on the Beijing-Shanghai railway, about mid-way between Shanghai and Nanjing.
longest bridge in the world was built in record time: laid in 2008, it was inaugurated in a solemn ceremony in 2011.The bridge connects the picturesque banks of Yangcheng Lake, the length of which in this place is a little less than nine thousand meters.The total length of the bridge and did amazing - more than 164 thousand meters, and the construction was carried out in a rather complicated geographical conditions, which demanded that the designers of innovative solutions to bring the work to its logical conclusion.
also in China is the longest bridge in the world, located above the water.This marvel of engineering joins the city of Qingdao and Huangdao Island.Even able to work without interruption Chinese spent on its construction for four years, but now, the assurances of experts, this is the longest bridge in the world will be valid for at least a hundred years, every day passing through several tens of thousands of machines.The designers have taken into account, and high seismic areas: a bridge across the Jiaozhou able to withstand an earthquake up to 8 points.
have something to brag, and our country.Open the eve of the APEC summit, the bridge connecting the mainland and the Isle of Russian Primorye, has both the longest guys (their length is 580 meters) as well as a huge span that is supported by the cables - 1.1 kilometers.Since its height above sea level was 70 meters, you can pass under it even the largest ocean liners.
However, the title of "the longest cable-stayed bridge in the world" belongs to the structure located again in China.It was opened 31 March 2012 in a festive atmosphere with an invitation not only political leaders, but also public figures, scientists and builders from around the world.This bridge is located above the gorge Aychzhay, and the length of its span exceeded the corresponding figures of the bridge on the Russian island of 72 meters.
Chinese engineers pay special attention to the fact that during the construction of this facility for the first time used the latest technology to keep working from the center to the ends of the bridge.This innovation made it possible to reduce considerably terms of reference works, so the bridge itself was put on half a year earlier than originally planned.
