A smart assembling vehicle works at "Linghang" large diameter shield tunneling machine at the construction site of the Chongming-Taicang tunnel, part of the Shanghai-Chongqing-Chengdu High-Speed Railway, under the Yangtze River, March 16, 2025. The ongoing excavation of the tunnel started from Chongming in east China's Shanghai Municipality to Taicang in Jiangsu Province. The length of the tunnel has surpassed 5,000 meters by Sunday, with a distance of only 660 meters to the middle of the river. The "Linghang" large diameter shield tunneling machine used for the construction is empowered by innovative technologies and its diameter is one of the world's largest in terms of shield tunneling machines for building high-speed railways.
