The 5.2-kilometre southern backbone road network, consisting of Yanhua Road (from Huanhu Fourth Road to Airport South Road) and Airport South Road (from Yanhua Road to Airport Motorway), is a crucial link between Ezhou's main urban area, Huanggang city and Ezhou Huahu Airport. To meet the deadline for the full opening of the road, the project management team and workers have worked tirelessly during the Mid-Autumn Festival and National Day Holiday to ensure timely completion.
