This three-tower spatial cable suspension bridge, with a main span exceeding 500 meters, is the world's longest-span single-column triple-tower suspension bridge. 

Recently, the Guangxi Cangwu-Rongxian Xunjiang Bridge, constructed by CCCC, was officially opened to traffic. This three-tower spatial cable suspension bridge, with a main span exceeding 500 meters, is the world's longest-span single-column triple-tower suspension bridge.

Stretching 1,688 meters, it closely connects Cangwu County and Rongxian County, which face each other across the river, supporting a new development pattern connecting the two bays.

Located adjacent to a water source protection area, the project team innovated drilling techniques to safeguard the clarity of the Xunjiang River and the habitat of its fish, delivering remarkable ecological achievements.

More importantly, the bridge has reduced travel time from over an hour to just 10 minutes. Residents on both sides no longer need to take detours, and agricultural products can now reach markets more efficiently—the fragrance of Cangwu tea and the sweetness of Rongxian fruit now travel far and wide across this once-daunting natural barrier.

This is not only a "bridge for people's livelihoods" but also a pathway of hope toward shared prosperity.
