The Jiaozi Pedestrian Bridge is located in the heart of the Chengdu Jiaozi Financial Headquarters Business District. As Chengdu's modern financial and business center, the district is positioned to be a world-class park city commercial district model.
How will this pedestrian bridge, located in Chengdu's Jiaozi Financial District, cross the Jinjiang River? Is it a bridge or a park? The starting point of the design is to constantly raise questions. First, let's return to the observation of the city's structure: The Jinjiang River flows from north to south, dividing the Jiaozi Financial Business District into two long rectangular blocks, east and west. The 2.5-kilometer-long Jiaozi green belt, extending in the east-west direction, is divided into two sections by the Jinjiang River, becoming parks facing each other across the river. The intersection of the Jinjiang River and the central green belt forms a natural breakpoint in the urban space, requiring a strong connection. The construction of a pedestrian bridge will not only connect the two banks, achieving the interconnection of the city's pedestrian system, but will also connect the Jiaozi green belt as one, achieving a "blue-green confluence" with the river.

The Jiaozi green belt is approximately 150 meters wide. As the part of the green belt that crosses the river, the bridge deck cannot be too narrow; otherwise, it will be difficult to form a continuous green axis. However, if a wide cross-section is adopted, it will inevitably cover the river channel and cast a large area of negative shadows. Therefore, we envisioned a "porous" bridge, allowing sunlight to penetrate the gaps in the bridge deck to illuminate the water surface.

Through a combination of unit addition and hole subtraction, the design ultimately achieved a collection form of "lotus bridge." Multiple cantilevered "lotus leaf" units achieve sufficient coverage width, while gaps are left between the discs, allowing sunlight, wind, rain, and sightlines to pass through, allowing the artificial bridge and the natural river to breathe in unison. Nine differently sized disc units are similar in shape but different in structure, ranging in area from 300 to 1600 ㎡. Trees are planted on them, connecting with the riverside green space to form a floating park suspended above the Jinjiang River. Walking among them, one experiences "lotus steps." The bridge's curves are dynamic and the combination of solid and void is interesting. The bridge deck and its reflection complement each other, and each cantilevered arc balcony becomes an interface for people to interact with the river.
