Preface
On June 30, the Shenzhen-Zhongshan Corridor was officially opened to traffic, and the traffic volume in the first hour of opening has exceeded 7,000 trips.
As a cross-sea passage connecting Shenzhen and Zhongshan and Nansha District of Guangzhou, the Shenzhen-Zhongshan Corridor shoulders the important task of connecting urban agglomerations on both sides of the Pearl River Estuary.
It took seven years to achieve the full completion of the main line at the end of November last year, and the whole line was opened to traffic at the end of June this year, and the Greater Bay Area has since erected a new "traffic backbone".
But at this time, some netizens also raised new questions, there is already a Hong Kong-Zhuhai-Macao Bridge, why will it cost 46 billion to rebuild the Shenzhen-Zhongshan Channel?
The Shenzhen-Zhongshan Corridor was opened to traffic, and the first hour ushered in the peak period
In the first hour of the opening of the Shenzhen-Zhongshan Corridor, the traffic volume created a new high, and it was warmly welcomed by everyone, who wanted to feel this "traffic backbone" for the first time.
The Shenzhong Corridor was originally known as the "Shenzhong Bridge", connecting Shenzhen and Zhongshan at both ends, but it was changed to the "Shenzhong Corridor" for various reasons.
Xinhua News Agency On June 30, 2024, the Shenzhen-Zhongshan Corridor, a major national project, was officially opened to traffic
The channel is located in the northern sea area of the Lingding Ocean estuary in the Pearl River Delta of Guangdong Province, spanning the Pearl River estuary, from Bao'an, Shenzhen in the east to Hengmen, Zhongshan in the west.
After the completion of the Shenzhen-Zhongshan Corridor, the distance from Shenzhen to Zhongshan has been reduced from two hours to 30 minutes, which is a full hour and a half shortened, bringing great convenience to the people's daily travel.
From the published pictures, it can also be clearly seen that the Shenzhong Passage floats above the Lingding Ocean like a streamer, with a total length of 24 kilometers.
The entire passage was built in the form of a tunnel to the east and a sea-crossing bridge to the west.
It is reported that if you want to pass through the Shenzhong Passage smoothly, you first need to go through a 6.8-kilometer-long undersea tunnel.
In the process, it is possible to observe the well-designed scenery without giving a dull and powerless feeling.
After that, you will cross the 17-kilometer bridge to the west, and you can enjoy the sea scenery along the way, which will bring a sense of joy.
During this period, it will also pass through artificial islands, which is why the "Shenzhong Bridge" was changed to "Shenzhong Passage".
There are many elements involved in the whole process, including tunnels and artificial islands, as well as bridges across the sea, so it is most appropriate to call it a "passage".
The Shenzhen-Zhongshan Corridor is a world-class cross-sea cluster project with the highest comprehensive construction difficulty, and the construction process is a great test of the construction team's ability.
Because the Shenzhen-Zhongshan Corridor adopts the scheme of "East Tunnel and West Bridge", the place where the submarine tunnel and the bridge need to be connected.
As a result, the West Artificial Island, which has an area of about 17 standard football fields, has emerged, which plays an important role in connecting the bridge and tunnel across the sea.
With a total length of 1,666 meters, the Lingdingyang Bridge on the west side of the Shenzhong Passage is now the world's largest full-span steel box girder suspension bridge in the offshore sea.
At the same time, the navigable net height of the Lingdingyang Bridge reaches 76.5 meters, which is the world's highest navigable clear space bridge in the sea.
Initially, in order to allow the smooth passage of ships, the design plan directly built a 270-meter-high main tower.
In addition, the Shenzhen-Zhongshan Corridor also has 8 lanes in both directions, which is completely based on the highway technical standard of 100 km/h.
The 30-minute journey has greatly shortened the travel time, and the Shenzhen-Zhongshan Corridor, which costs 46 billion yuan, has played its role since June 30.
Xinhua News Agency On December 28, 2016, the construction of the Shenzhen-Zhongshan Corridor of the Pearl River Estuary Cross-sea Passage Project started with a total investment of 46 billion yuan
In addition to these, the designers also took into account the issue of safe passage at the beginning of construction.
There are three holes in the tunnel wall from top to bottom, which are equipped with wires, fire lines, and communication lines respectively to fully ensure the safe use of the tunnel.
Although the design of the Shenzhong Passage is very perfect and has created many of the world's bests, it is inevitable that some netizens will raise questions.
Some netizens said that there is already a Hong Kong-Zhuhai-Macao Bridge, why do you want to rebuild a Shenzhen-Zhongshan Channel?
"Copy" of the Hong Kong-Zhuhai-Macao Bridge?
As the name suggests, the Hong Kong-Zhuhai-Macao Bridge is a bridge and tunnel project connecting Hong Kong, Zhuhai and Macau.
The main bridge is 29.6 kilometers long, and the Hong Kong port to Zhuhai-Macao port is 41.6 kilometers long, which also directly shortens most of the travel time.

The Macao-Zhuhai-Macao Bridge is also built in accordance with the standards of expressways, with a speed of 100 km/h for vehicles in motion, and a total investment of 126.9 billion yuan.
By the beginning of 2024, the Hong Kong-Zhuhai-Macao Bridge will have a single-day inbound and outbound passenger flow of 144,000 people, and an average of 18,000 vehicles will pass through the bridge every day.
This data also proves that the Hong Kong-Zhuhai-Macao Bridge plays an important role in the daily travel of the masses, minimizing the waste of time.
Now it took 7 years and spent 46 billion yuan to rebuild and build the Shenzhen-Zhongshan Corridor, which has also aroused doubts from some netizens, and is even directly called "a copy of the Hong Kong-Zhuhai-Macao Bridge".
After digging deeper, you will find that although the Hong Kong-Zhuhai-Macao Bridge and the Shenzhen-Zhongshan Corridor have many similarities, the emphasis is different.
The smooth opening of the Shenzhen-Zhongshan Corridor has brought great convenience to the traffic on both sides of the Pearl River Estuary and effectively alleviated the traffic pressure of the Humen Bridge and the Jinshamen Bridge.
At the same time, the construction of the Shenzhen-Zhongshan Corridor has allowed the two ports to communicate with each other, officially entering the era of "half-hour living circle", so that the Greater Bay Area can gradually realize the "one-hour living circle".
In addition, it can also integrate the cooperation and innovation on both sides of the Pearl River Estuary to the greatest extent, providing a broad development space for the development of both sides.
In addition, the Shenzhen-Zhongshan Corridor connects the Yangtze River Expressway with Shenzhen Airport, realizing an efficient intermodal mode of sea, land and air integration.
This measure ensures that the services of the two ports remain stable and the transshipment distance is greatly shortened.
At the same time, Nansha can also quickly integrate into the Shenzhen metropolitan area, effectively driving the industrial linkage with some areas of Zhongshan.
The successful construction of the Shenzhen-Zhongshan Corridor not only shortens the distance, but also represents a big step forward in the connectivity and cooperation of the Greater Bay Area, laying a solid foundation for future development.
epilogue
The smooth opening of the Shenzhen-Zhongshan Corridor is of far-reaching significance, which will make the exchanges between the two places more frequent, and will promote the development of the two cities to the greatest extent.
At the same time, in the process of construction, Shenzhong has successively set several "world's best", which fully proves that China now has strong strength.
Despite the difficulties ahead, China will choose to rise to the challenge and overcome the unknown.
This move also allows the world to intuitively see the strong strength of China's infrastructure, and the title of "infrastructure madness" is worthy of its name.
Not only that, the opening of the Shenzhen-Zhongshan Corridor will also lay a solid foundation for the future development of the Greater Bay Area, and move towards a longer-term future.
I believe that after that, there will continue to be good news to prove to the world that China's demeanor as a great power will be revealed.
