bridges

Although Arab Emirates and Saudi Arabia are immersed in a war for have the highest skyscrapers in the worldwhen we talk about megaconstructions, there is no one to have China. It doesn’t matter if we talk about tunnels, Dams, roads and even half -skyscraper. And, when we talk about bridges, there yes There is no rival. From time to time They complete a new pharaonic bridgebut if there is something that shows China’s muscle about it, they are the bridges of the Beijing-Shanghái line. Because it is in it where the three longest bridges are located in the world. Massive and … boring? He Great Danyang-Kunshan bridge It is the longest bridge in the world. It measures just over 164 kilometers and can also be the most boring bridge in the world. The reason is that it is a bridge in which functionality prevailed. It is part of the high -speed network that joins Beijing and Shanghai and in its construction, 10,000 workers used 450,000 tons of steel and 2.3 million m3 of concrete to give life to a structure that had to endure possible ships of ships and the impact of earthquakes. It has 2,000 pillars, 22 tunnels, it has an average altitude of just over 30 meters and trains circulate at a speed of more than 320 km/h. Declaration of intentions. The most striking thing is that it only took four years to complete the work. It is an achievement if we consider that other bridges, such as the Constitution of Cádizthey took more than seven years for about three kilometers. They began in 2006 and the works were completed in 2010, inaugurating both the bridge and the line in 2011. The investment? 8,500 million dollars, and although in later bridges we have seen an aesthetic intention by the engineers, that of Danyang-Kunshan was a declaration of intentions. It became a global reference in rail engineering, but above all in a sample of the Technological advance of the country when undertaking the Infrastructure construction large scale in record time. It is something that has also attracted attention to subsequent works, the speed at which things do, especially, in many occasions of works of great complexity. In dark red, the bridge. In clear red, part of the full line Beijing-Shanghai, a monster. Because although this bridge Have the Guiness record in length and it was an important technical advance, the most imposing thing is that it is only a piece of the puzzle that supposes the high -speed line Between Beijing and Shanghai. It is a connection with a length of 1,318 kilometers and, apart from that of Danyang-Kunshan, there are three other bridges that are on the list of the 10 longest in the world. He Great Bridge of Cangde measures 115.9 kilometers and the Great Tianjin Bridge It “stays” at 113.7 kilometers. The three are the longest in the world, and in the seventh place on the list is the Great Bridge of Beijingwith 48.2 kilometers. The four were completed for the inauguration of the line in 2011, assuming a pharaonic work and, in total, representing a third of the total line length. The artificial island of the Hong-Kong-Zhuhai-Macao bridge, which is a bridge over the water until it becomes a submarine “bridge” It is called obsession. Because, if we look at the list of the longest trains in the world, China is a constant, monopolizing with eight structures the top ten positions. Not only are they very long bridges to house train lines (the Weinan Weije It has 102.7 kilometers, but it is not from the Beijing-Shanghai line), also for roads. The fifth longest bridge in the world is Hong-Kong-Zhuhai-Macaohe longest maritime bridge With 55 kilometers (and, this yes, quite attractive), the eighth of the list is the Quingdao Haiwanwith another 44.5 kilometers of road and the tenth is the bridge of line 1 of the Wuhan Metro with 37.7 kilometers. Within those positions of honor, we only find a 54 -kilometer Thai bridge, the Band Na Expresswayand the Lake Pontchartrain Road in the United States with 38.4 kilometers.
