| Abstract: | A mountain bridge is located near Yuyang Pass, Wufeng County, Yichang City, is a control project of Yidu - Laifeng Expressway (Yichang Section) and is also a key project of Yuyang Pass Ring Highway in Provincial Highway 242. The project is proposed to adopt a 480-m span double-layer steel truss girder cable-stayed bridge to span a typical deep-cut V-shaped valley. The project overview, main technical standards and engineering characteristics of the bridge are introduced, and the design of overall scheme for the bridge is discussed. |
