Learning from the bridges of the great water town of ZhuJiaJiao, or those from the delicate gardens in Suzhou, we decided to link both sides of the 50 meters wide river with a bent path. The bent axis responds to different access conditions and visually adapts to the surroundings.

Our strategy of borrowing from local historical references and other variables of the site, together with the objective of revealing the structural performance of the bridge, will generate the final form of the project.

The load-span relation recommends the use of the metal truss. In order to resist the strong torsion stress associated with the support-less winding shape of the bridge, we activate structurally all the sides of its distorted volume. Both shores of the river have a contrasting character. This fact is emphasized via designing asymmetric constraints for the structure. The bridge has a simple support on the transversal ramp that faces the rapid and narrow street at the northern access. Courtesy of Ca-Group – Plan
On the contrary, there is a stiff connection with the longitudinal ramp that connects to the slow and large southern square. The elevation of the bridge adapts itself to the resulting asymmetric diagram of bending momentum. Trying to minimize the amount of different steel se...
