is also built, under the site of future new Terminal project - "Terminal 4". However, Airport North Station is inaccessible to or from any of the airport facilities. Line 20 (Shenzhen International Exhibition Center Conveyance Project) links Airport North Station on Line 11 with services to Chongqing Road, International Exhibition Center South, International Exhibition Center North and International Conference Center stations. Line 20 opened in December 2021. Guangzhou–Shenzhen intercity railway is currently under construction, and planning to provide services from Shenzhen Airport Station and Shenzhen Airport North Station. In the future, Shenzhen–Maoming High-Speed Railway and Hong Kong–Shenzhen Western Express Railway are planned to stop here.

Airport express shuttle bus There are many bus routes between the airport and the urban area, most of them via expressways and only cost ￥10 yuan.
