Vehicles run on the recently renovated Loujiang Avenue expressway in Suzhou, Jiangsu province. The intercity expressway, which was upgraded last week, serves as a faster conduit between Suzhou and Kunshan, Jiangsu, as it cuts the distance by 40 percent. Built by China Railway Construction Corp's 24th bureau, the 20.2-kilometer route features China's prefabricated bridge-building solutions, using 688 factory-made segments assembled with AI-guided precision to slash labor needs by 60 percent and reduce construction time by six months.
