China is known as an infrastructure madman. Today, the scope of China's infrastructure has covered new concepts such as 5G, big data, and clean energy. But what people feel most is the high-speed rail, airport, highway and other aspects that are closely related to people's travel. Behind these miracles are the efforts of several generations of scientific researchers. Only in terms of transportation, China's infrastructure has infinite possibilities. Among them is such a super project. Although it has not yet started, in order to ensure the success of the construction, China has spent as long as 27 years formulating research plans and plans to invest 300 billion yuan in it. What project is it? The scale of this investment is comparable to that of the Three Gorges Hydropower Station. Why hasn't the construction started?

Bohai Bay Cross-sea Channel

For a long time, the separation of the Bohai Strait and the economic exchanges between the north and the south have been restricted by the underdeveloped local traffic conditions. The links between the Northeast and Shandong and the Pearl River Delta have been restricted by it, not to mention the economic and trade between the North and the South. How inconvenient it is to travel. In addition, it is precisely because the two places, with a straight line distance of only more than 100 kilometers, could only face each other across the sea, so the original population migration was a major project in order to solve the problems of people’s livelihood and economic development. , China Construction Corporation began to put forward the idea of the Bohai Bay cross-sea channel.

According to the concept, this channel is more than 120 kilometers in length, from Yantai, Shandong to Lvshun, Dalian, Liaoning. It uses a cross-sea bridge, subsea tunnel or a combination of bridge and tunnel to cross the Bohai Strait to make up for the type C traffic that once existed. , So as to make the traffic from Yantai to Dalian more accessible.

So, why hasn't this project been started? In fact, from a general perspective, although this project can connect the economy of the Northeast and the coastal areas and drive the development of the Northeast, it will also affect some cities, such as Tianjin, Qinhuangdao, Tangshan and other cities. When the port goes out to sea, the passage of bridges and tunnels restricts the navigation of large freighters, and maritime transportation is also extremely inconvenient. In addition, the difficulty of construction of the project is also a reason. Any accidents in the fault zone and strong earthquake zone will cause serious consequences.

However, even so, the positive significance of this project to people is still very great. Therefore, before the official start of construction, the Chinese side first built a test project from Penglai, Shandong to Changshan Islands. The straight-line distance between these two areas It is 7,000 meters long and the geological conditions are relatively superior. The construction scope is within Yantai city, which reduces coordination costs. Moreover, the investment amount of this test project is about several billion yuan, combined with China’s richness in the construction of the Hong Kong-Zhuhai-Macao Bridge. With experience and technology, this project will not only become the world's first cross-sea vacuum pipeline, but also the first underwater bridge. With the completion of this test project in the future, the Bohai Sea Cross-sea Channel will be just around the corner from the day it is fully completed. .

In the future, the construction of the Bohai Bay Cross-Sea Passage Project will positively promote the economic development of the eastern coastal areas of China. At the same time, it will also promote the formation of an economic integration development pattern in the regional urban agglomerations on both sides of the Bohai Bay. This cross-sea channel has the meaning of ensuring transportation safety and national defense strategic traffic. It can not only promote the exchanges between Shandong and Dalian, narrow the gap between the North and the South, but also meet the growing needs of the people. It is completely based on the people’s livelihood. Super project. Editor/He Yuting
