1. Nanjing Yangtze River Bridge: China's New Wonder of the 20th Century
Explore the Nanjing Yangtze River Bridge - the first of China's two new wonders. This is the first dual-layer railway and highway bridge on the Yangtze River, designed and built entirely by China. With a total length of 6,772 meters and remarkable engineering achievements, this bridge is not only a symbol of modernization and technological progress but also holds immense economic, political, and strategic significance.
Learn about the 8-year construction process, from 1960 to 1969, involving 3.84 million cubic meters of concrete and 66,500 tons of steel, costing 280 million yuan. This bridge has become a cultural icon with numerous artworks and monuments, deeply connected to the special memories of many generations of Chinese people. Marvel at the bridge's beauty and significance in the region's modern transportation system.
2. "Nanjing Third Yangtze River Bridge" or "Nanjing No.3 Yangtze Bridge"
Explore the Nanjing Third Yangtze River Bridge in Wuhan, an impressive engineering marvel with groundbreaking design and construction technology. This is China's first dual-track railway bridge with eight lanes, integrating dedicated passenger lines, urban railways, and main urban roads, showcasing advanced and comprehensive transportation planning.
With a main span of 1.23 km and a total investment of 8.8 billion yuan, the bridge features two decks: the upper deck is an eight-lane highway, and the lower deck is a two-way four-lane railway. What makes it special is that it is the world's first cable-stayed bridge to use an asymmetrical twin-tower design, with one tower standing 155 meters tall and the other 130.5 meters tall.
During construction, the project overcame ten of the world's most challenging technologies, laying a solid foundation for China's future bridge projects. The completion of the three bridges in Wuhan and the Nanjing Third Yangtze River Bridge has significantly improved railway and highway network planning, alleviated road traffic pressure, and marked a new height in China's multi-purpose bridge construction capabilities
3. Wufengshan Yangtze River Bridge: An Engineering Marvel Defying All Limits
Explore the Wufengshan Yangtze River Bridge - an unexpected engineering marvel in China, where powerful suspension cables lifted a 10,000-ton bridge, challenging all limits and creating a wonder. With a total length of 6,408.9 meters and a soaring main span of 1,428 meters, this bridge showcases the incredible strength and innovation of human ingenuity.
This specially designed dual-layer structure includes an upper deck with an eight-lane two-way highway, while the lower deck houses a four-track high-speed railway, marking a pinnacle of engineering and architecture. With a construction process lasting five years and setting no fewer than seven world records, the Wufengshan Bridge stands as a living symbol of resilience and determination, a clear testament to the ability to overcome any challenge and conquer all limits.
To ensure stability, the bridge uses main cables with a diameter of 1.3 meters, appearing from a distance like two strands but capable of bearing a load of 170,000 tons, equivalent to lifting three fully-loaded Liaoning ships. China's reputation in infrastructure is truly well-deserved.
