China's tunnel machine finishes Yangtze crossing

The world's largest tunnel boring machine by diameter successfully completed boring a tunnel beneath the Yangtze River in China, connecting Shanghai and Taichang City, with a length of 14.25 kilometers. This achievement represents a historic milestone, as it will allow high-speed trains to travel under the river at speeds of up to 350 kilometers per hour without reducing speed, thereby enhancing the regional transportation network. The water tunnel itself is 11.325 kilometers long and is expected to be completed by the end of 2026. Once finished, it will reduce the travel time between Chongqing and Taichang to 17 minutes, significantly improving the area's transportation infrastructure.
