ZZHK Architects: Ruyi Bridge is located at Tianfu 2nd Street near the Jian’nan Road intersection in the High-tech Zone of Chengdu, south of CR Phoenix City. The bridge crosses Tianfu 2nd Street, and the main bridge is facing the greenway of Dayuan Central Park.
There are 2 spans of the main bridge crosses Tianfu 2nd Street. To facilitate the pedestrian crossing, both sidewalks disposed spiral stairways with inclination 1:4 to 1:12. On the other hand, in order to connect the greenways on both sides of the street, 2 bicycle ramps are installed with inclination 1:12 at the ends of the main bridge.
The bridge connects Dayuan Park on the south to the urban space and green landscape on the north side. The pedestrian and bicycle lanes are connected and continued.
The design concept is called Sound of Panpipes, as the facade design is inspired by the Chinese Panpipes witch is one of the traditional Chinese musical instrument. The undulations and fluttering of the body are like the flow of music rhythm, fresh and elegant. It shaping a functional urban sculpture.

Viewed from the air, the bridge seems just like a Ruyi embedded in the city. Ruyi, a Chinese traditional S-shaped ornamental object, usually made of jade, formerly a symbol of good luck. Bridge like this shape with the meaning that all things are going smoothly and good luck. In May 2016, this bridge was subordinated to the Chengdu High-tech Zone Major Landscape Improvement Project and was reported by many media. It was officially named “Ruyi Bridge”. The project was completed in February 2018, and was re-focused on a number of media outlets with the Chengdu Hi-tech Zone Green Road Signature Node.

The bridge is of Ruyi-shape in plane. The 42 metres long Tianfu 2nd Street-crossed section is a precast steel box girder with uniform section. There are 2 spans of the main bridge crosses Tianfu 2nd Street, the central pier is arranged at the green belt in the middle of the road, the side pier is arranged in the sidewalk and the outer green belt. The design span combination of Tianfu 2nd Street- crossed section is 21m+21m.
There are three lines arranged on the plane. Line A starts from Dayuan Park, crosses Tianfu 2nd Street and lands in the greenway on the north side. The overall length of Line A is 213m, reserved 0.55m width on both sides of the bridge deck, installed the railings and light poles, widen the partial of the split pier. The bridge is arranged in three links:

Line B starts from Dayuan Central Park, connects with the second link of Line A and joins into it. The overall length of Line B is 76m, adopted reinforced concrete continuous hollow slab, reserved 0.55m width on both sides of the bridge deck, installed the railings and light poles. The bridge is arranged in two links: the first span arrangement is 12+9m=21m, beam height 0.6m; the second one is 9.5+13+12+12m=46.5m, beam height 0.6m, navigable clear width 2.7~4.49m.

Line C starts from the pedestrian green belt on the north side of Tianfu 2nd Street, connects with the third link of Line A and joins into it. The overall length of Line C is 42m, reserved 0.55m width on both sides of the bridge deck, installed the railings and light poles. The bridge is arranged in one link: adopted reinforced concrete continuous hollow slab, the span arrangement is 3×10m=30m, beam height 0.6m, navigable clear width 2.36~3.15m.

The overall length of the bridge is 331m, the abutment is connected with U-shaped groove. The Tianfu 2nd Street-crossed section is provided with bi-directional 1% longitudinal slope which is toward both sides of the road, the drainage cross slope is bi-directional 1%. By requirement of the bridge use function, set wheelchair access according to the implementation requirements of non-motor vehicle. The ramp slope of the bridge is 7%~15%, and the drainage cross slope is 1% in both directions.
