Xidayinggang Twin Bridge, as photographed by Montse Zamorano

CA Group Xidayinggang Twin Bridges


These twisting twin bridges are the work of the Shanghai-based CA Group, but the photographs of the bridges are the work of photographer Montse Zamora. The bridges look a little bit like the double helix of DNA to me, but I’m a bit of a science nerd and it turns out that they’re inspiration is more geographical than biological. The form of the bridges is a reference to mountains which are absent in this particular region of China. The shape also suits the structural system of the arched suspension bridge. What’s unique about this bridge is that the arches jump from side to side, making the bridge more dynamic while also ensuring that they have the same sort of formal legibility from more angles. And the angles of these bridges are captured very well by Montse.

Although she is now based in Madrid, Montse did live in Shanghai after graduating from the Escuela T├ęcnica Superior Arquitectura with a Master’s degree focused on Architectural Photography (her thesis Ezra Stoller y Julius Shulman: Dos miradas enfrentadas contrasted the work of the two folks who might be the most widely celebrated photographers of modernism.) And her photographs of the two tripple-span, sextuple-arch bridges at Xidayinggang are simultaneously straightforward and dramatic. Seen rising from a field of bright and optimistic flowers, the graceful arcs of the bridge start to resemble the mountains the designers describe as inspiration, varied and complex in a way that natural features often are. We can only hope that these mountain bridges will stand long and are built well; built to withstand the environment that would see them crumble as a result of natural forces, corruption or a debilitating collusion of both.
