The Beijing and Amsterdam-based architectural studio NEXT has completed the ‘Lucky Knot’ pedestrian bridge, a shiny red shoelace offering knots and ripples on the Dragon King’s Harbor River in Changsha, China.
There is nothing predictable about the new bridge in this wavy form in China. There is no starting and ending point where a bridge with an infinite loop in the 185-meter spine is evident. The bridge designer, Michel Schreinemachers, partner of Next Architects, described the bridge as “an ending figure” as they referred as a Mobius ring for the bridge. The red steel bridge, 24 meters high, has a rising and falling structure along the river to allow views of Lake Meixi, the city, the park, and the surrounding mountains. This braided structure has not only a turning cycle of a Mobius ring, but also a Chinese art of decorative art at the same time. In addition, old decorative Chinese folk art symbolizes luck and welfare.
NEXT Architects designed Lucky Knot bridge within the development plan of 6.5 million square meters planned by Kohn Pedersen Fox in the southwest direction of the city for the Changsha’s Meixi Lake region. Actually in this project, three bridges are primarily linked as a unified, meaning that Next allowing three forms to function as a unique structure. Schreinemachers knew that the bridge height is at least 23 meters tall from the river level to allow the craft to pass under the bridges. He also knew that the steepest line would be no more than 34 degrees, to keep stairs pedestrian friendly. In the light of these parameters, hekept the bridge paths wide and the curves flatter.
Bridge’s 1.001 step connects four different public spaces. As you can see in the picture above, there is a separate access point for the bridge in its area.
Schreinemachers said, “Once we developed the basic shape of the bridge, the main challenge lay in designing the intersection that enables pedestrians to go from one route to the other,” Schreinemachers says. The bridge overlaps at five connection points. These provide structural support and serve as pathways by which pedestrians can access different routes. To get from one bridge to the next, people can walk through moon gates, the circular passageways used in traditional Chinese garden architecture.
Authorities said “The bridge was an integral part of the process, combining the knowledge and expertise of the Dutch team on infrastructure and water management and the local context of the Chinese team.”, “The bridge has already become an icon in just one week.”
