Hunnan Avenue Expressway is the Shenyang Ring II South Shifting Phase I Project, and is an important part in the "ring + radiation" expressway networks of Shenyang. By analyzing the overall planning and project construction conditions of expressways in Shenyang, the design of Hunnan Avenue Expressway Project is completely set forth from the aspects of project background and general situation, main technical standards, overall scheme, bridge and tunnel engineering. The overall design scheme shows that Hunnan Avenue Expressway and the surrounding built expressways can initially form the expressway network system, which can support the outward distribution of urban functions and effectively improve the traffic congestion of urban central area.
