A team led by professor Xu Weiguo at the Tsinghua University School of Architecture in Beijing has 3D-printed a 26.3-metre-long concrete bridge, which they claim is the world’s longest.
The 3.6-metre-wide pedestrian bridge, which spans a canal in Shanghai’s Baoshan District, was installed earlier this year. It was designed by Tsinghua University School of Architecture’s Zoina Land Joint Research Center for Digital Architecture (JCDA), and built by Shanghai Wisdom Bay Investment Management Company.
