The picture shows the Wong Ju Wan Interchange
Highway traffic is the most important factor restricting the development of modern cities, in the expansion of the city area, the existing highway system can not meet the requirements of the line, the construction of overpasses has become the best choice, now many large-scale cities in China have built their own overpasses, and some netizens said that the most complex maze overpass built in China is located in Chongqing, it is the Huangjue Bay overpass, it is said that this overpass has as many as 20 forks and eight traffic directions, the height of up to 5 floors, the structure is extremely complex, Many foreigners who have just arrived in Chongqing have been directly confused, so how complicated is the HuangjueWan overpass? Can't the United States really build a similar overpass? Some Chinese netizens said that the emergence of the Huangjue Bay overpass is the product of the combination of China's strong comprehensive national strength and the local special situation in Chongqing, which can be said to be unique in the world.
Chongqing has the title of mountain city, the city was initially located in a small plain embraced by mountains, and later with the continuous expansion of the city scale, the entire urban area was forced to begin to develop on the peak, so it has formed a complex traffic situation in the local area today, the HuangjueWan overpass is one of the typical representatives, at the beginning the section of the overpass is only 4 directions, and later with the development of the city, the direction and number of forks in this section of the road continue to increase, and the pressure of highway traffic is also increasing. The local government was forced to invest in the construction of the overpass, and the Wong Ju Wan interchange became the most complex interchange in the world as soon as it was completed.
In order to meet the existing and future traffic needs of the city, the scale of the HuangjueWan interchange is extremely large, the entire overpass from top to bottom has a total of 5 levels of bridge deck, leading to 8 different urban directions, each direction has more than two forks, the entire overpass has a total of 20 forks, far away it looks like an intricate maze, newcomers are very easy to get lost, and because each line leads to different directions of Chongqing, once lost on this overpass, I am afraid that you can only come to Chongqing half-day self-driving tour.
Although such a complex overpass solves the traffic problems faced by the city, it obviously brings new troubles to the travel of residents, why should such a complex overpass be built locally? In fact, this is also a local helpless move, as mentioned earlier, Chongqing is built between the mountains, because of the narrow area of the plain, the city can only continue to develop in the direction of the mountainside in order to get more development space, resulting in the traffic system of Chongqing is very twisted and complex, and the overpass serving the urban transportation system can only be built very complex.
In fact, China has not thought of solving this problem, at present, Chongqing has carried out a lot of exploration, such as the Chongqing light rail that became an internet celebrity some time ago, the light rail train on the ground can share a large part of the ground traffic pressure, and the subway under construction in Chongqing can also share the pressure of the highway, after having these public transportation facilities, the local traffic problem will be greatly alleviated.
In order to fundamentally solve the complex problem of Chongqing's transportation system, perhaps China needs to carry out larger-scale super projects, such as flattening the surrounding mountains and filling in the valleys, and manually clearing out a large mountain plain for urban development, but obviously China is not able to complete such a large-scale project, and hopes that China can find better solutions in the future.
