Changtai Yangtze River Bridge, Arch and cable-stayed road-rail bridge in Changzhou and Taixing, Jiangsu Province, China.
The Changtai Yangtze River Bridge spans approximately 6.4 miles (10.3 kilometers) across the Yangtze River, connecting Changzhou and Taixing with a main cable-stayed span measuring 3,858 feet (1,176 meters) and towers reaching 1,155 feet (352 meters) in height.
Construction of the bridge began on January 9, 2019, and after six years of work involving innovative building techniques and multiple world records, it opened to traffic on September 9, 2025.
The bridge represents a landmark achievement in modern Chinese infrastructure development, embodying the country's commitment to improving regional connectivity and supporting economic growth throughout the Yangtze River Delta region.
The bridge features a two-level design with an upper deck carrying a six-lane expressway and a lower deck accommodating both an intercity railway capable of speeds up to 124 mph (200 km/h) and four lanes for regular vehicular traffic, reducing river crossing times from over an hour to just 20 minutes.
This structure holds the distinction of being the world's longest cable-stayed bridge and features an innovative asymmetrical lower deck design that balances a heavy railway system on one side with a regular roadway on the other through precise cable tension adjustments.
