Shanghai Yangtze River tunnel

The Shanghai Yangtze River Tunnel is a major underwater roadway connecting the city of Shanghai with the Pudong New Area across the Yangtze River. It consists of two parallel tunnels—one for cars and another for trains—allowing seamless transportation across the river. These tunnels are engineered to withstand water pressure, seismic activity, and environmental factors, ensuring safety and reliability. They significantly reduce travel time, easing traffic congestion and supporting Shanghai’s economic growth. Construction involved advanced tunneling techniques, and the project highlights China's expertise in large-scale infrastructure development.
