Airport North Station on Line 11 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. In the future, Line 20 (Shenzhen International Exhibition Center Conveyance Project) will link Airport North Station on Line 11 with services to Chongqing Road, International Exhibition Center South, International Exhibition Center North and International Conference Center stations. The construction of Line 20 is suspended as for early 2019.
