This municipal pedestrian bridge adopts the structural form of steel box girder and steel box arch, its total area is 4180㎡.

The design notionoriginates from the conception of "infinite ring" – the Mobius. We abstractly project the infinite formin four-dimensional space into three-dimensional space, forming the icon of infinity in mathematics.

This icon represents the unlimited development possibilities of the Chengdu High-tech Zone where the bridge is located.

In terms of structure, the bridge body is divided into main bridge and auxiliary bridge. The main bridge is 346.89m in length and 4.65m-9.88m in width connecting greenways on both sides of the river for cycling.

While the auxiliary one is 208.78m in length and 6m-14.53m in width where there exist the crescent-shaped theater steps for the river scenery, providing a different space experience for the public.

As far as the night scene lighting, designers just did concise atmospheric modern floodlighting to highlight the unique shape of this bridge, hoping to present a different landmark over Jin River.

BRIDGE STRUCTURE

Wuchazi bridge is divided into two parts. The upstream bridge is the main bridge, and the downstream bridge is the auxiliary bridge. These two parts are connected by channels. Specifically speaking, the main bridge has two sections.

The first one is a two span continuous steel box girder bridge (27m+27m), while the second one is a four span slant legged rigid frame bridge (28.5m + 75.347m + 84.152m + 44.73m) to meet the navigation and flood discharge requirements.

The auxiliary bridge adopts steel structure and is designed as three spans. The first and second spans are special-shaped steel box arch bridges with spans of 59.166m and 84.431m respectively, which meet the requirements of navigation and flood discharge.
