China is advancing construction on the Zhangjinggao bridge over the Yangtze River, a massive engineering project designed to set a new world record upon its scheduled completion in 2028. The central span of the bridge will reach 2,300 meters in length, surpassing the current record holder—Turkey’s Çanakkale bridge across the Dardanelles strait—by 277 meters.
Engineering Specifications and Route Details for the Zhangjinggao Bridge
The Zhangjinggao project forms part of a new road connection crossing the Yangtze River in the Jiangsu province, aiming to improve communication and reduce travel times between several cities. The Yangtze is one of the most important waterways in China. According to a communication published by the Chinese agency Ziniu in June 2026, the bridge will strategically connect Zhangjiagang, Jingjiang, and Rugao. The infrastructure features a total crossing length of 7,859 meters over the Yangtze River, incorporating the south channel bridge, the north channel bridge, and access bridges with eight lanes in both directions. The south channel bridge functions as a double-tower suspension bridge carrying the main span across the primary river channel.
Did You Know?
The main span of the south channel bridge will measure 2,300 meters between its primary towers, supported by main cables spanning 4,400 meters, 350-meter-tall towers, and 3,017-meter steel box girders. This suspended distance between the towers is the specific measurement that will allow the structure to achieve the world record in its category.
Investment and Construction Progress on the Yangtze River Crossing
Construction requires massive anchorage systems capable of supporting the main cables and distributing the forces generated by the weight of the deck, traffic, and weather conditions. By June 2026, work on the north anchorage of the south channel bridge had reached an advanced stage, with crews focusing on cable supports and anchorage blocks. This project operates as part of broader national investments in transportation infrastructure. Data distributed by the state agency Xinhua indicates that during the first quarter of 2026, the country allocated roughly 330 billion yuan—equivalent to about 48 billion dollars—toward major transportation initiatives.
Ziniu described the south channel bridge as the “world’s largest bridge project” due to its design and scale.
Answer questions about the 2028 Zhangjinggao bridge project completion
When is the Zhangjinggao bridge scheduled for completion?
The project is scheduled to be completed in 2028, at which point it is expected to become the longest suspension bridge in the world.
How long will the main span of the bridge be?
The main span of the south channel bridge will reach 2,300 meters in length, which is 277 meters longer than the current record-holder, the Çanakkale bridge in Turkey.
Which cities will the project connect?
The bridge will create a strategic connection uniting the cities of Zhangjiagang, Jingjiang, and Rugao across the Yangtze River.
How might the completion of this eight-lane corridor alter commercial transport and daily commuting patterns across the Jiangsu province once it opens in 2028?
