The team at the Tsinghua University School of Architecture in Beijing created aconcrete bridge 26.3 meters long using 3D printing . According to the authors of the project, it is the longest bridge of its kind in the world.

The bridge connects the shores of the canal in Shanghai, its width is 3.6 meters. It consists of 176 concrete blocks, which took 450 hours to print, and has a monitoring system that will monitor the concrete’s deformation over time.

In this case, the cost of construction amounted to about two thirds of the cost of building a conventional bridge of the same size.

The arched shape of the building is inspired by a 1,400-year-old bridge in Zhaosiang, but it is assumed that it marks a step towards a new technology that is increasingly used in construction.
