The world’s longest 3D-printed concrete pedestrian bridge has been completed in Shanghai. Designed by Professor Xu Weiguo from the Tsinghua University (School of Architecture) – Zoina Land Joint Research Center for Digital Architecture, the 26.3-meter-long bridge was inspired by the ancient Anji Bridge in Zhaoxian, China.
The single-arch structure was created using a 3D printing concrete system developed by Professor Xu Weiguo’s team, integrating digital design, cost efficiency, smart technology, and architectural dynamism. Enclosing the 3.6-meter width, the bridge’s handrails are shaped like flowing ribbons on the arch, creating a light, elegant movement across the Shanghai Wisdom Bay pond.
