The first phase project of Tianbao Avenue West Extension Line is located in the southwest of Shuangliu District, starting from the current Chengxinpu, and ending from the Tongwei section of Huangjia Street, which has been built. The west section of the designed Industrial Park Avenue is connected to the current Shuangxing Avenue, and finally connects to the Tianfu New District directly, forming the east-west main road of Shuangliu District. The implementation of the project will set up the main road network structure in the southwest of Shuangliu District and provide conditions for the development of the surrounding plots.

The total length of the project is about 11.7km, the road grade is the main trunk road, the design speed is 60km/h, the road red line width is 40m, and the green belt is 30m on both sides (the green belt width is 15m in the local limited location). The project includes road engineering, traffic engineering, culvert engineering, bridge engineering, drainage engineering, lighting engineering, electrical engineering, landscape engineering and large road node crossing bridge.

Along the road, natural landforms such as farmland and water (canal) system are passed, and the planning nature of the surrounding area is green land, industrial land and residential land. The area along the road is undeveloped land, and the current situation is farmland. The main intersection road is Dawei Road, while Chengmian Lekezhuan and Metro Line 10 are across the project.
