On June 30, 2024, this historic moment finally arrived, and the world's high-profile super project, the Shenzhen-Zhongshan Corridor, was officially opened for trial operation. This cross-sea cluster project, which integrates "underwater interconnection of bridges, islands and tunnels", is not only the pinnacle of engineering technology, but also the crystallization of China's wisdom. With a total length of about 24 kilometers, the route is like a giant dragon lying across the Pearl River estuary, closely connecting Shenzhen and Zhongshan.
What used to take nearly two hours to travel from Shenzhen to Zhongshan now takes just 30 minutes to bring people from both places close at hand. Such a speed change not only greatly shortens people's travel time, but also promotes economic and cultural exchanges on both sides of the Pearl River Estuary.
The construction process of the Shenzhen-Zhongshan Corridor is full of hardships and challenges. After 141 days, the west artificial island was successfully closed; 80,000 tons of immersed tubes were accurately installed on the seabed at one time...... Behind these seemingly simple numbers are the countless days and nights of hard work of tens of thousands of builders. They braved the wind and the huge waves, and struggled at the mouth of the Pearl River for seven consecutive years. Frequent typhoons, high salt and humidity environments, and complex seabed conditions...... These difficulties and challenges have not stopped them from moving forward. The deep passage is not only the crystallization of their hard work, but also the spiritual symbol of their perseverance and courage.
This is one of the most difficult cross-sea cluster projects in the world, and now stands proudly at the mouth of the Pearl River, showing the world the brilliant achievements of China's transportation construction!
The Shenzhen-Zhongshan Corridor is a super project under construction, which will connect the cities of Shenzhen and Zhongshan in Guangdong Province and become a new artery on both sides of the Pearl River. The construction of this corridor is of great significance for promoting economic development and regional integration in the Pearl River Delta region.
Construction of the Shenzhen-Zhongshan Corridor began in 2016 and is expected to be completed and opened to traffic in 2024. It is about 24 kilometers long, including 6.8 kilometers of undersea tunnels, 17.2 kilometers of bridges, and two artificial islands. With a design speed of 100 kilometers per hour, the passage will significantly shorten the travel time between Shenzhen and Zhongshan from 2 hours to about 30 minutes.
The construction of the Shenzhen-Zhongshan Corridor will play a huge role in promoting the economic development of the Pearl River Delta region. It will strengthen the ties between Shenzhen and Zhongshan and promote industrial cooperation and resource sharing between the two places. At the same time, it will further improve the transportation network in the Pearl River Delta region, improve the transportation efficiency of the region, and provide more convenient conditions for economic development.
In addition to economic significance, the construction of the Shenzhen-Zhongshan Corridor also has important social significance. It will provide a more convenient way for residents in the Pearl River Delta region to travel, and promote the flow of people and cultural exchanges within the region. At the same time, it will also bring new opportunities for the development of tourism in the Pearl River Delta region and attract more tourists to come for sightseeing.
The construction of the Shenzhen-Zhongshan Corridor is a highly technical project, and it needs to overcome many technical difficulties. For example, the construction of undersea tunnels needs to solve the problems of waterproofing, ventilation, and seismic resistance of tunnels; The construction of bridges needs to take into account the impact of the marine environment, such as waves, tides, sea breezes, etc. In order to solve these technical problems, the engineering team adopted many advanced technologies and processes, such as immersed tunnel technology, large diameter shield technology, etc.
The construction of the Shenzhen-Zhongshan Corridor is a major project in the Pearl River Delta, which will play a huge role in promoting the economic development and social progress of the region. We look forward to the early completion and opening of this passage to bring more convenience and opportunities to our lives.
