Chinese engineers rotated a bridge span 60 degrees over Shanghai’s active maglev line with high precision, completing a key rail project.
Chinese engineers completed the first large-span bridge rotation over an active high-speed maglev line in Shanghai, rotating a beam 60 degrees at the Chuansha grand bridge during a four-hour overnight window.
The operation, part of the Shanghai-Suzhou-Nantong Railway phase II, avoided disruptions to the maglev line and Yingbin highway.
Using cantilever casting and advanced monitoring systems, the team achieved precision with axis deviation under 5 mm and joint errors below 2 mm.
The 111.8-kilometer railway, designed for 200 km/h traffic, will enhance regional connectivity in the Yangtze River Delta.
Environmental safeguards were implemented throughout construction.
