The Dong'an Lake Sports Park Bridge, which is situated in Dong'an New Town, Longquanyi, in the central "Eastward" area of Chengdu and serves as the venue for the 31st Chengdu FISU World University Games opening ceremony, was completed by the Chengdu-based architecture firm Atelier-Sizhou.

Xianshu Jin and Jia Liu, the founders of Atelier-Sizhou, take visitors on a journey to Chengdu where they reconsider the function of bridges in congested areas and rethink the connection between design and user experience.

The park has three gyms and one stadium: an aquatics center, a multipurpose gym, and a multiball game gym. The main stadium can hold 40,000 spectators.

Connect “One Stadium Three Gyms” with open spaces

The bridge will increase traffic flow during the FISU Games, and the terrace will link the stadiums and gyms. The bridge's post-FISU Games focus will be on enhancing public space and playground interactions, improving accessibility, enhancing the surrounding environment, and creating more room for operations.

Connecting “One Stadium Three Gyms” with open spaces

Space form

The bridge forms a visual experience of varying elevations when walking, extending from the terrace of the stadium and gyms. The children's playground is encircled by the bridge, which descends spirally to the site's center, creating an enclosed area. 

A range of platform heights are used in the middle section to provide good vantage points, and the entrance and exit connect to outdoor areas. As the bridge interacts with the public space, it creates a variety of visual and spatial experiences.

Main structure

A 1000mm thick steel box girder serves as the bridge's main structural component, supporting a 20–30m long hexagonal, v-shaped column. The primary structure's orange hue draws attention to the movement trend while contrasting with the surroundings.

Corridor skin

Two steel plates, each 3 mm thick, are joined to form the bridge skin. The orange hue of the main body and the greenery surrounding it are reflected by a white sheet, giving the impression of a lighter volume. Lighting is positioned between two sheets to add a deep layer of nocturnal light to the bridge.
