The Changtai Yangtze River Bridge, the world's largest span cable-stayed bridge, recently underwent a critical load test on its combined road-rail section—an essential assessment to verify structural integrity and load-bearing performance before the bridge opens to traffic.
As the first double-deck bridge over the Yangtze River integrating an expressway, an intercity railway, and a regular highway, the structure stretches 10.03 kilometers in length, with a main span of 1,208 meters and a main tower rising to 352 meters. It adopts a hybrid structure of steel and steel-concrete composite elements.
The load testing, conducted in phases over the course of a week, covered six bridge sections, including the cable-stayed bridge, navigation bridge, non-navigable spans, and approach bridges.
Construction of the bridge began in 2019 and is expected to be substantially completed in the second half of this year. The roadway section will open first, cutting travel time between Changzhou and Taizhou from the current 1 hour and 20 minutes to just 20 minutes.
