During this period, there are 7 interchanges, 7 separated interchanges and 4 extra large bridges, which is a suburban ring expressway connecting Shanghai to Shanghai, Jiangsu, Zhejiang, Shanghai Qingping and Shanghai-Hangzhou. According to the requirements of Shanghai highway network planning, the construction standard of this section is expressway, and the design speed is 100 km/h, in which the Anting-Shanghai-Hangzhou expressway section has six lanes in both directions and the subgrade width is 34.5 meters; The section from Shanghai-Hangzhou Expressway to Nong Xin is a two-way four-lane highway with a subgrade width of 28 meters.

In fact, there are many relevant road networks in the planning of Tongsan Expressway, and the Shanghai section of Tongsan Expressway is the relevant road network, not the main road. After Tongsan crossed the Yangtze River in Jiangyin, the main roads planned are Xicheng Expressway-Huning Expressway-Zhajiasu Expressway-Hangzhou Bay Bridge-Hangzhou-Ningbo Expressway-Yongtaiwen Expressway.
