China has officially inaugurated the Changtai Yangtze River Bridge in Jiangsu Province, establishing the world’s longest cable-stayed bridge and significantly reducing travel times across the Yangtze River. The monumental 10.3-kilometer structure, which connects Changzhou and Taizhou, is notable as the first on the Yangtze to integrate an expressway, a local road, and an intercity railway into a single, comprehensive transport artery.
Engineering Milestones
Constructed over six years, the Changtai Bridge project represents a significant feat in modern infrastructure, drastically cutting the journey across the Yangtze from over an hour to approximately 20 minutes. With a main span stretching 1,208 meters, this new link sets multiple world records, showcasing advanced engineering capabilities.
Innovations during its development included achieving the fastest sinking speed for large caissons and developing the world’s first intelligent tower crane with a lifting capacity exceeding 10,000 tonne-meters. The project also advanced industrialized construction techniques for steel-concrete composite pylons.
Further demonstrating precision engineering, the team designed the world’s largest-tonnage deck crane, enabling millimeter-level accuracy during installation. The bridge’s structural integrity is highlighted by its 350-meter-high, diamond-shaped towers, built from steel and concrete for optimal stability.
Its foundations were specifically reinforced to withstand the powerful currents of the Yangtze River, ensuring long-term resilience. The Changtai Bridge also holds records as the longest-span combined road-rail steel truss arch bridge and the longest continuous system of steel truss girders globally.
Regional Impact
The opening of the Changtai Yangtze River Bridge underscores China’s ongoing commitment to advanced infrastructure development and its engineering prowess. Officials anticipate this new artery will play a crucial role in facilitating regional trade and transportation, further integrating the economic landscape of the Yangtze River Delta.
