The Changtai Yangtze River Bridge, currently under construction, is a composite road-rail structure integrating a central cable-stayed span with two flanking arch bridges. Spanning 5,299 meters in total length, the main bridge complex represents a multifunctional transportation hub. Its design features a central navigation channel bridge with a 1,208-meter main span cable-stayed configuration, which upon completion will hold the world record for the longest-span combined road-rail cable-stayed bridge.

     The project’s auxiliary spans - the Tianxingzhou and Lu'anzhou Channel Bridges - employ steel-truss arch designs with 388-meter main spans, establishing them as the world’s longest-span composite road-rail steel arch bridges. All structural elements utilize an innovative stacked deck system: the upper level accommodates a dual six-lane expressway, while the lower tier simultaneously supports a dual-track intercity railway alongside a dual four-lane Class I highway.

     This multi-tiered arrangement enables independent operation of high-speed rail and vehicular traffic within a single structural footprint, optimizing river navigation clearances while addressing diverse transportation demands through its engineered vertical stratification.
