The recently inaugurated Shenzhen–Zhongshan Link stands as a testament to modern engineering marvels, connecting two major cities on the Pearl River Delta (PRD): Shenzhen and Zhongshan.
This expansive bridge-tunnel structure is not only a pivotal infrastructure project but also a record-breaking achievement, setting an unprecedented 10 world records.
Breaking World Records
The Shenzhen–Zhongshan Link, completed in June 2024, is a 49.7 km marvel of modern engineering, featuring a blend of bridges and tunnels that seamlessly connect Shenzhen and Zhongshan.
This ambitious project, which started in May 2017, came with a hefty price tag of US$4.83 billion but promises unparalleled benefits for the region’s connectivity and economic growth.
1. Longest Combined Bridge-Tunnel System
The Shenzhen–Zhongshan Link is the longest combined bridge-tunnel system in the world, stretching 49.7 km. This extensive structure includes a 6.7 km tunnel and 19 bridges, with the longest continuous bridge section spanning 22.5 km.
2. Largest Over-Water Highway Bridge
Additionally, the Shenzhen–Zhongshan Link features the largest over-water highway bridge, covering approximately 15.5 km above the sea. This segment alone showcases the sheer scale and ambition of the project, offering breathtaking views and a direct route across the Pearl River Delta.
3. Highest Number of Bridge Piers
With 19 bridges included in the Shenzhen–Zhongshan Link, the project boasts the highest number of bridge piers in any single infrastructure project. This intricate network of supports ensures the stability and longevity of the bridge, even under the most challenging conditions.
4. Most Expensive Bridge-Tunnel Project
Moreover, at a cost of US$4.83 billion, this is the most expensive bridge-tunnel project ever undertaken. The investment reflects the project’s complexity and the high standards required to complete such a monumental task.
5. Fastest Construction Timeline
Remarkably, completed in just over seven years, the Shenzhen–Zhongshan Link holds the record for the fastest construction timeline for a project of its scale. This rapid development was made possible by cutting-edge construction techniques and efficient project management.
6. Longest Immersed Tunnel
Furthermore, the 6.7 km tunnel section of the Shenzhen–Zhongshan Link is the longest immersed tunnel in the world, demonstrating China’s capability to execute underwater construction on an unprecedented scale.
7. Widest Bridge Deck
The Shenzhen–Zhongshan Link features the widest deck, accommodating eight lanes of traffic (four in each direction). This design ensures smooth traffic flow and significantly reduces travel time between Shenzhen and Zhongshan.
8. Highest Speed Limit for a Bridge-Tunnel
Notably, with a maximum speed limit of 100 km/h, the Shenzhen–Zhongshan Link allows for faster travel compared to other similar structures, making it the bridge-tunnel with the highest speed limit globally.
9. Most Advanced Safety Features
The Bridge incorporates the most advanced safety features ever used in a bridge-tunnel project. These include state-of-the-art monitoring systems, emergency response mechanisms, and robust construction materials to withstand natural disasters.
10. Greatest Reduction in Travel Time
One of the most significant achievements of the Shenzhen–Zhongshan Link is its impact on travel time. It has reduced the journey between Shenzhen and Zhongshan to less than 30 minutes, a dramatic improvement over previous travel options.
The Pearl River Delta Region
The Shenzhen–Zhongshan Link is more than just a bridge-tunnel; it represents a new era of connectivity and progress for the Pearl River Delta region. By setting these 10 world records, the project highlights China’s commitment to innovation and its ability to tackle some of the most challenging engineering feats.
The Shenzhen–Zhongshan Link
As the Shenzhen–Zhongshan Link opens to the public, it stands as a beacon of modern engineering and a symbol of what is possible when ambition meets innovation.
