Abstract:Expressway is located at the top of four levels of urban roads, which fully serves the transportation function and is a road solving the large capacity, medium and long distances, and fast transportation in cities. The construction type of expressways requires a comprehensive impact assessment based on different regions and situations. Through the design of the Moganshan Expressway in Hangzhou, and starting from the traffic volume analysis, the scale and level of the expressway are determined. Then, from the connection with the starting and ending points, the impact on ground bridges and the rail transit, and two types of elevated expressways and tunnel expressways are compared and demonstrated. The selection of expressway types under the relevant restricting conditions is analyzed.
