Shenzhen-Zhongshan Bridge, also known as "Shenzhen-Zhongshan Bridge", is a bridge under construction connecting Shenzhen City and Zhongshan City in Guangdong Province, China. The hub has a total length of 24 kilometers, including a 6.8 kilometers long immersed tube tunnel; the design speed of the deep and medium passage is 100 kilometers per hour. It is a component of the Shenzhen-Cenxi Expressway (National Expressway G2518) of China's national expressway network.

The Shenzhen-Zhongshan Passage is expected to be completed and opened to traffic in 2024. After opening to traffic, it will only take 30 minutes to go directly from Shenzhen to Zhongshan. It will completely change the history that people in western Guangdong must pass the Humen Bridge to Shenzhen and greatly reduce the traffic pressure of the long-term congestion of the Humen Bridge. Both Shenzhen and China have simultaneously entered the "half-hour life transportation circle" to promote the rapid development of the urban agglomeration in the Guangdong-Hong Kong-Macao Greater Bay Area in the fields of humanities, logistics, economy, and culture, as well as the interconnection of transportation.

In December 2020, on Niutou Island, Guishan Town, Zhuhai, the first “Big Mac” pipe joint weighing about 60,000 tons after prefabrication and “processing” has been slowly transported from the pouring area by 200 intelligent marshalling trolleys. The shallow dock area of the immersed tube prefabricated smart factory of the Deep-Medium Corridor staged a magical scene of "ants moving elephants" on the project site, and the construction of the Deep-Medium Corridor has repeatedly broken through the world's problems.

At present, the construction of the deep and middle passage is smooth, the bridge project has completed all the main bridge pile foundation works, and the construction of the cap is underway; the construction of the island has been completed on the west artificial island, and the construction of the main structure of the CW2 section of the buried tunnel on the island is underway; The island has completed the construction of the temporary cofferdam structure of the weir construction section, and the construction of steel sheet piles and steel pipe piles for high-speed protection along the river. For the core equipment of the immersed tube tunnel, the construction tasks of the transportation and installation integrated ship (one voyage Jinan 1), the gravel leveling ship (one voyage Jinping 2), feeder ships, and anchor boats have been completed. The project is expected to be completed and opened to traffic in 2024 .

After the opening of the Shenzhen-Zhongshan Passage, it will become an important passage connecting the east and west banks of the Pearl River. It will quickly go directly from Zhongshan to Shenzhen. The commuting time has been reduced from 2 hours to 30 minutes. In addition to greatly reducing the traffic pressure on the Humen Bridge, it will also completely change the direction of Zhanjiang in western Guangdong. , Maoming, Yangjiang people must pass through the traffic bottleneck of Humen in and out of Shenzhen.

Commodity housing prices in Zhongshan are only about one-fifth of Shenzhen's, and office rents, industrial land and commercial land prices are only about one-eighth of Shenzhen's. The two places have large gradients and complementary spaces. Planning construction and shortening commuting time, Zhongshan will also become the back garden for the production and life of Shenzhen residents.
