The New River Canyon Bridge in the United States is a 518 m long span steel truss arch bridge with a main span of 1,900 m. Built in 1977, it is the largest steel-truss arch bridge with similar span type in the same bridge type. The largest bridge span of the same type in China is under construction Daning River Bridge, the main span of 400 m. The paper briefly introduces the design, construction and maintenance of the New River Gorge Bridge some of the information for domestic bridge engineers reference.
