 This section first opened in October 2000, and is so named because it connects the city centre with Nanning's international airport, Nanning Wuxu International Airport.As this section was built prior to the other sections, it uses different exit numbers than those employed on the rest of the expressway (in which kilometre zero is at the San'an interchange).Instead, the exit numbers reset, with the Gaoling interchange serving as kilometre zero for this section.
