On June 21, 2021, the Zengcheng-Tianhe section of the Zengcheng-Foshan Expressway in Guangzhou. The project route starts at Zhucun Street, Zengcheng District, Guangzhou City. Tan, Xiancun, Ningxi, Zhongxin, Yongning, Huangpu District, Xinlong, Changling, Lianhe, and finally Taihe Town, Baiyun District, and connect to Zengfo Expressway (Baiyun-Foshan section) westward, about 38.4 kilometers long , The total investment is 1.89 billion yuan!

The route includes 6173m/4 extra-large bridges (including the main interchange bridge, the same below), 10937.2m/23 bridges; 1921m/1 long tunnel (the average length of two tunnels, the same below), 475.5m/1 short tunnel ; Set up Yanshiling (hub), Yamada, Shuangxifeng (hub, reserved), Zhucun, Ningxi, Fengcun (hub), Huangling, Yonglong, Huangdeng (hub), Jintianlong (hub), There are 11 interchanges in He Pai; 1 management center, maintenance work area and concentrated accommodation area (co-built on the same site), and 1 service area.

The highway technology standard is adopted for the whole line, the design speed is 100 km/h, the subgrade width is 36 meters, the bridge width is 35.5 meters, and the tunnel construction boundary (single hole) has a clear width of 18 meters. The design vehicle load level of bridges and culverts on the whole line adopts highway-I level, and other technical indicators should comply with the relevant regulations of the "Highway Engineering Technical Standards" (JTGB01-2014) promulgated by the Ministry of Transport.
