[2] In 2014, the Guangzhou Municipal Planning Bureau revealed that it was studying the extension of Line 8 through to Jianggao station, and then along National Highway 107 to Guangzhou North Railway Station in Huadu District.

The project was approved by the National Development and Reform Commission in late March 2017.

However, project was somewhat controversial as experts and the public have expressed doubts about the extension plan from an operations perspective, as with the completion of the North-North Extension, the total length of Line 8 from Guangzhou North Station to Wanshengwei station will exceed 50 kilometers.

The first section of Line 24 is planned to start construction in 2021 and be completed in 2025.

[6][7] Line 24 is part of Phase 3 adjustment plan of Guangzhou Metro, now under review by the National Development and Reform Commission as of September 2022.
