Did you know this bridge stands as a testament to modern engineering? We are standing before Songkeng Bridge. This bridge represents more than just a passage. It embodies innovation and connectivity.
The Shenzhen-Zhongshan Link includes Songkeng Bridge. This link opened in June 2024. It drastically cuts travel time between Shenzhen and Zhongshan. What used to be a two-hour trip now takes only about 30 minutes. This transformation results from an impressive combination of bridges and tunnels.
The entire Shenzhen-Zhongshan Link stretches 24 kilometers. It integrates two bridges, two artificial islands, and an underwater tunnel. This makes it one of the most complex construction projects worldwide. The link boasts eight lanes. Vehicles can travel at speeds up to 100 km per hour.
The Shenzhen-Zhongshan Link has already seen significant use. In its first month, over 3 million vehicles crossed it. This highlights its importance in the Guangdong-Hong Kong-Macao Greater Bay Area. The bridge joins the Guangshen Expressway to the south of Shenzhen Airport. It also connects to the Jihe Expressway to the east of the airport.
The Shenzhen-Zhongshan Link project boasts ten world records. These records are not just about size. They represent groundbreaking achievements in engineering and construction.
One record is the largest span for a fully offshore steel box girder suspension bridge. It measures 1,666 meters. Another record is the highest bridge deck at 91 meters. The bridge also has the highest navigation clearance for a sea bridge.
The project used the largest offshore suspension bridge anchors. Each anchor contains approximately 344000 cubic meters of concrete. The bridge also underwent the highest wind resistance test. It withstood wind speeds of 83.7 meters per second.
The Shenzhen-Zhongshan Link also features the longest two-way eight-lane immersed tube tunnel. It stretches 5035 meters. This tunnel is also the widest underwater steel shell-concrete immersed tube tunnel. It measures up to 55.6 meters.
A large volume of self-compacting concrete was poured. It was for a steel-shell immersed tube. The project also includes the world’s first underwater expressway interchange. It also has an airport interchange.
The project used the widest repeatedly foldable M-shaped waterstop. It was used in the final joint of the immersed tube tunnel.
The Shenzhen-Zhongshan Link is a vital transportation project. It enhances connectivity in the Greater Bay Area. The project showcases China’s expertise in engineering. It offers solutions for global transportation challenges.
The opening of the Shenzhen-Zhongshan Link reshapes the Pearl River Estuary’s road network. It significantly impacts the economic and social development. This link helps transform the area into a world-class city cluster. It also aims to be a global technology and innovation center.
As we stand here, we can appreciate the magnitude of this achievement. Songkeng Bridge is not just a structure. It is a symbol of progress and innovation. It connects cities and drives economic growth. It is a marvel of modern engineering.
