The Western Delta Route is a 97.9km closed system expressway developed in three phases with a total of six lanes in dual directions. It is the only main expressway artery between the city centres of Guangzhou and Zhuhai, and offers the most convenient access to Hengqin, Macao and Hong Kong through its connection with Second Hengqin Bridge, the Zhuhai Link Road and the HZM Bridge. As the expressway artery in the developing regional expressway network on the western bank of the PRD region, it continues to benefit from the healthy economic development of peripheral cities.
