The Yarlung Zangbo River Bridge under construction
The Yarlung Zangbo River Bridge, located in Jiacha County, Tibet Autonomous Region, is a double-track railway bridge with a design speed of 160 km/h and a 430-meter half-through concrete-filled steel tubular arch. The bridge deck is 3,344 meters above sea level, with a maximum daily temperature difference of 25℃. Situated in an 8-degree earthquake area with steep terrains, it becomes the longest-span concrete-filled steel tubular arch bridge in the world, with the highest altitude and seismic intensity. It is the first time in China that coating-free weather-resistant steel has been used in the main structure of railway bridges, which ensures the bridge is corrosion resistant for 100 years without the use of protective coatings. The bridge was completed and opened to traffic on June 25, 2021.
International Bridge Conference (IBC), sponsored by the Engineers' Society of Western Pennsylvania, is an international academic conference with high reputation and wide influence in the world bridge industry. Launched in 1988, the annual IBC awards commend outstanding projects and individuals in global bridge industry in terms of design, practicality, concept, environmental resources, etc.
