Dongshuimen Yangtze River Bridge, Combined truss and cable-stayed bridge in Chongqing, China
The Dongshuimen Yangtze River Bridge is a combined truss and cable-stayed bridge spanning 1,125 meters across the Yangtze, connecting Yuzhong and Nan'an districts with a dual-deck structure. The upper deck carries four vehicle lanes while the lower deck accommodates two rail transit lines.
Construction of the bridge started in December 2009 and reached completion in March 2014, marking a major step forward in regional transport. The project demonstrated new approaches to spanning large rivers with combined road and rail systems.
The bridge towers draw inspiration from traditional Chinese weaving shuttles, blending local craftsmanship with modern engineering design. This approach shows how the city weaves its cultural heritage into contemporary structures.
The upper level operates with a speed limit and serves vehicle traffic, while the lower level is dedicated to rail transit. Pedestrians and cyclists can cross using separate paths that provide views over the river.
The bridge features an innovative cable anchor beam system used for the first time in bridge engineering. The 36 inclined cables are made of 139 parallel steel strands, showcasing advanced engineering techniques.
