The reconstruction project of Jinhai Expressway is about 7km long and connected with Middle Yanggao Road Interchange. A S20 interchange is newly built. There are four pairs of up and down ramps newly built in the whole line. The functional positioning and service objects of the project, the main technical standards, the route direction, and the node schemes are briefly discussed, especially in the case where the layout of elevated bridges is mainly controlled by shield tunneling sections and station structures of rail transit, as well as the influence of high-voltage lines. The schemes for route design and cross-sectional layout of road are analyzed in order to provide the experience and reference for similar projects.
