2. Project construction content and scale construction content: road engineering, bridge engineering, drainage engineering, lighting engineering, greening engineering, transportation facilities engineering, etc.
The project starts from the interchange of the east bridgehead of Chaoyang Bridge in the west and Hongdu Avenue in the east. Among them, the viaduct section is adopted to the west of Xianghu Lake, and the viaduct + ground auxiliary section is adopted to the east of Xianghu Lake. 6km, width 25m, area of about 150,000 m2, ground auxiliary road length of about 1.8km, width of 16m, area of about 28,800 m2, 3 interchanges across the entire line, namely Taohua Road Interchange Interchange, Yingbin Avenue Diamond Interchange, Hongdu Avenue- Jinggangshan Avenue-Sandian West Road Interchange Assembly.
