Dong‘an Lake Sports Park is located in Dong’an New Town, Longquanyi, the core area of Chengdu’s “Eastward”, which is the venue for the opening ceremony of the 31st Chengdu FISU World University Games. The park contains “one stadium and three gyms” — a main stadium with a capacity of 40,000 people, an Aquatics Centre, a Multi-Purpose Gymnasium, Multi-Ball Games Gymnasium. During the FISU Games, the bridge focused on improving traffic efficiency, and stadiums and gyms will be connected via the terrace.

After the FISU Games, the bridge focuses on the interaction with the public space and the playground, increasing accessibility enriching the landscape, and providing additional space for the operation after the games. The bridge extends out from the terrace of the stadium and gyms, forming a visual experience of different elevations during walking. The bridge spirals down to the centre of the site, and surrounds the children's playground, forming an enclosed space with a sense of enclosure. In the middle section, different height platforms are designed to create good viewing points and the entrance and exit to open spaces.

The bridge forms various spatial and visual experiences while interacting with the public space. The main structure of the bridge is a 1000mm thick steel box girder, with a hexagonal v-shaped column spanning 20m to 30m. The orange color of the main structure creates contrast with the environment while highlighting the movement trend. The bridge skin comprises two 3mm thick steel plates tied together. The white sheet reflects the orange color of the main body and the green color of the surrounding, which makes the volume looks lighter.

Lightings are placed between two sheets, giving the bridge a rich layer of illumination at night.
