The taste for mega constructions in China is well known. Not only because it allows them to teach the power of national engineering but also because they create structures worthy of transforming themselves into mass tourist attractions such as the Eiffel Tower or the San Francisco Bridge.
The last mega-construction inaugurated in the Asian country is an elevated bridge 218 meters above a valley and 488 meters long in the province of Hebei. Built by the firm Bailu Group, the presentation ceremony was attended by nearly 3,000 tourists who were able to see in person how it feels to walk on a transparent bridge between two cliffs within the Hongyagu National Park.
With these measures, the Hongyagu is the longest bridge in the world, capable of withstanding earthquakes of 6 degrees of magnitude and hurricanes of force 12 according to the Beaufort scale. Now, what other bridges or mega constructions does China have that can break records? We discover them below.
Until the Hongyagu bridge was opened, the longest bridge in the world was in the Zhangjiajie National Park, a structure 430 meters long and 300 meters high. It is located in the Natural Park of Zhangjiajie, in the province of Hunan, which is recognized since 1992 as a World Heritage Site by Unesco, being one of the most visited in China.
Jiaozhou Bay Bridge
The Qingdao Bridge, the longest over water on Earth, was erected over Jiaozhou Bay. Its construction took the record of another Chinese bridge, the one located in Hangzhou Bay, which until now was considered the longest in the world over the waters of the sea, with 36 kilometers in length.
This mega-construction has a length of 42.5 kilometers and has six lanes through which traffic flows in both directions. It has more than 5,200 pylons, and millions of tons of steel and concrete were needed for its manufacture. Currently, a small artificial island is being built next to the Qingdao Bridge, which serves as a rest area for travelers, so they can refuel their cars, have a snack or do some shopping.
The longest tunnel in the world for public transport is located in Guangzhou, another major city in the south of the country. This mega-construction allows you to travel 60 kilometers by subway without surfacing.
Beipanjiang Bridge or Duge Bridge
The Beipanjiang bridge is not suitable for those who suffer from fear of heights. It is located 565 meters above the canyon of the Nashua River, in the south of the country, and connects the provinces of Yunnan and Guizhou in two hours when once there were cities that were five hours away by car.
The photographs that can be taken from the surroundings of the Beipanjiang Bridge are spectacular. The mist between the mountains stretches across the landscape as if to engulf the bridge that was born between the rocks.
Liupanshui or Beipan River Shuibai Railway Bridge
This bridge holds the title of the highest railway bridge in the world. It was opened in 2001 and is located in Liupanshui. In 2009 it lost its highest arch bridge title in the world but still retains the aforementioned.
Special mention deserves the method followed for its construction, which was described as super-efficient. The reason is that instead of using two temporary towers in each stirrup to build the arch, it was made in two halves on formwork, each one on one side of the ravine. The first stack of each end helped as a tie.
Once the halves of the arches were finished, the piles were turned 180º until facing the arches. Then the halves were put together, and the board and the rest of the piles were built.
It is a marvel of civil engineering in the city of Jishou suspended over the Hunan Dehang canyon 355 meters above the ground. At 1,176 meters long, it connects the ends of two tunnels that make up the Jishou-Chadong autoroute, built above a beautiful valley.
The Karakoram, The Highest Highway
To finish the post from above we will talk about Karakoram, a highway and mega-construction at 5,000 meters high that connects the west of China and the north of Pakistan through one of the most dangerous and steep areas of the continent because it crosses three large mountain ranges such as the Karakoram mountain range, the Pamir mountain range and the Himalayas.
As regard, the route along which the Karakoram highway goes formed part of the Silk Road in the past and in the present, it is considered as a symbol of cooperation and friendship between both countries.
