China Unveils World’s Longest Cable-Stayed Bridge Over the Yangtze River Revolutionizing Travel and Regional Growth

Published on September 11, 2025

In the latest China travel news, the Changtai Yangtze River Bridge has made headlines as the world’s longest cable-stayed bridge. Stretching 10.3 kilometers (6.4 miles) across the Yangtze River, the bridge connects the cities of Changzhou and Taizhou in Jiangsu Province.

This remarkable infrastructure project significantly reduces the travel time between the two cities—from over an hour to just 20 minutes. Aside from easing local travel, the bridge is expected to boost tourism and stimulate regional growth in the area, making it a significant development in China’s ongoing infrastructure projects.

What Makes Changtai Yangtze So Special?

The Changtai Yangtze River Bridge is more than just a transportation link—it’s a feat of modern engineering. With a main span of 1,208 meters (3,960 feet), it now holds the record as the longest cable-stayed bridge in the world. This bridge combines an expressway, a regular road, and an intercity railway, all on a single structure. It’s the first time such a design has been used on a bridge of this scale, making it an important milestone for both infrastructure and engineering.

An Innovative Engineering Achievement

What makes the Changtai Yangtze River Bridge stand out is its innovative design. Unlike traditional bridges that place the heavier railway in the center, the Changtai Yangtze River Bridge has a unique asymmetrical design, with the high-speed railway on one side and a regular road on the other. This design posed several engineering challenges, but the project team solved these by adjusting the tension of the supporting cables and calibrating the bridge’s prefabricated segments. These adjustments allowed for the successful completion of a structure that not only accommodates multiple transport systems but does so efficiently.

Key Features of the Changtai Yangtze River Bridge:

• Length: 10.3 kilometers (6.4 miles)
• Main Span: 1,208 meters (3,960 feet)
• Transport Systems: Expressway, regular road, and intercity railway on one bridge
• Design: Asymmetrical, with rail and road on separate sides
• Construction Time: Six years

Addressing the Challenges of Asymmetry

The decision to place the railway and the road side by side was an unusual choice that posed multiple engineering challenges. Typically, a heavier rail system is placed in the center, with roads on either side. This standard design helps balance the load of the bridge. However, in urban areas, the roadways often need to curve to connect to the city’s network, wasting valuable land. The engineers of the Changtai Yangtze River Bridge rethought this design, coming up with a solution that maximized efficiency and land use. By adjusting the tension of the cables supporting the railway and carefully calibrating the prefabricated segments, the team managed to ensure that the bridge remained stable throughout the construction process.

In addition to its unique design, the team behind the Changtai Yangtze River Bridge used cutting-edge technology to complete the project. For example, engineers developed a satellite-guided tower crane to place materials with high precision. They also built the world’s largest bridge-deck crane, capable of positioning massive sections of the bridge with millimeter-level accuracy. These tools were essential in making sure the project came together as planned, turning an ambitious design into reality.

Building for the Future

The Changtai Yangtze River Bridge is not just about size; it’s also built to last. The foundations of the bridge are designed to withstand the powerful currents of the Yangtze River, ensuring that the bridge remains stable and functional even in challenging conditions. The bridge’s towers are made from steel and concrete and are designed in a diamond shape for added strength. The structure also features flexible joints, which allow for movement in response to temperature changes. This level of planning shows that the Changtai Yangtze River Bridge is built for the long haul, providing vital infrastructure for future generations.

The Global Significance of the Longest Cable-Stayed Bridge

Before the Changtai Yangtze River Bridge, the title of the longest cable-stayed bridge in the world was held by the Russky Bridge in Vladivostok, Russia. The Russky Bridge spans 3.1 kilometers and has a main span of 1,104 meters. The Changtai Yangtze River Bridge surpasses this by having a main span of 1,208 meters. But it’s not just the length that makes this bridge impressive. Its design makes it more suitable for urban areas, as it combines rail and road traffic in a way that maximizes space and efficiency.

This bridge is also part of a larger plan to expand China’s bridge network across the Yangtze River. With over 150 bridges already in place, the goal is to increase that number to 240 by 2035. This expansion will enhance transportation across the region and provide a significant boost to regional growth.

Conclusion: A Milestone in China Travel News

The completion of the Changtai Yangtze River Bridge is a significant milestone in both engineering and infrastructure development. As the longest cable-stayed bridge in the world, it sets a new standard for bridge design and construction. Not only does the bridge improve travel time between Changzhou and Taizhou, but it also plays an important role in stimulating regional growth and boosting tourism in Jiangsu Province.

As China continues to build and modernize its infrastructure, the Changtai Yangtze River Bridge will stand as a symbol of the country’s commitment to progress. It’s not just a physical structure but a crucial part of the ongoing development of the region and a key player in the future of transportation across the Yangtze River. For anyone following China travel news, the opening of this bridge is an exciting development that will shape the future of travel and connectivity in China.
