With planning underway, construction will begin in 2022 at a cost of 48.6 billion yuan ($7 billion), announced the Zhuhai Natural Resources Bureau in September.

In addition to the Nansha-Zhuhai (Zhongshan) rail line, two high-speed railways and four other intercity MRTs are designated to run through Zhuhai in the Guangdong-Hong Kong-Macao Greater Bay Intercity MRT Construction Plan.

The Zhuhai-Jiangmen section of the Zhuhai-Zhaoqing high-speed railway will come under construction in 2022. Preliminary research is being done on the Guangzhou-Zhuhai (Macao) high-speed railway before construction begins in 2021.

The Guangzhou-Zhuhai Intercity MRT has been in service since 2011. The Gongbei-Chimelong section of Zhuhai Airport Urban Rail Transit opened in August, while the Hengqin-Airport section is under construction. The Shenzhen-Zhuhai and Guangzhou-Foshan-Jiangmen-Zhuhai intercity MRTs are currently undergoing preliminary research.
