Abstract:The traffic pressure is building up because of urban framework expansion continuously. Therefore, the existing roads are required to widen and reconstruct. Taking the widening reconstruction of Wuling Mountain Avenue (Zhangqing Highway) in Zhangjiajie as an engineering case, its construction background, project overview and main technical standards are introduced. Through the prediction of engineering traffic flow and the demonstration of scale, the overall scheme of the project is studied. Based on the functions of the different road sections, the cross-sectional patterns of four road sections from Ziwu Road (starting point) to the county road X018 (end point) are arranged respectively. On the basis of fully considering the connection with the surrounding lands, four nodes of University Town Elevated Bridge are designed. The summarization shows that the local planning, present situation, excavating and filling balance, functions of different road sections, and situations of surrounding lands are also fully considered in the design process of the project and at the same time to meeting the smooth traffic in order to perfect the regional road network structure and drive the economic development along the line.
