It won’t be built for another two years, but it’s already generating buzz! The first 3D-printed pedestrian bridge in Singapore is slated to be unveiled in 2028, spanning the Jurong River and connecting two new residential districts. This project, led by the Land Transport Authority (LTA) in collaboration with the Singapore Centre for 3D Printing at Nanyang Technological University, aims to address the labor shortages plaguing the construction industry.
The bridge is expected to be 10 meters long and 5 meters wide. It’s the culmination of several years of research, as the project began in January 2023, with an investment of over $1.4 million. A mixture of concrete, sand, and water has been developed to be extruded by a robotic arm.

The bridge is composed of 10 segments, or blocks, which are printed and then assembled. Each segment requires four hours of printing and offers a 50% reduction in labor. These blocks interlock using high-strength steel cables. The duration of this assembly stage has not been specified.
