The Guangzhou Metro opened three new lines and one extension at the end of 2017.
Line 9 has opened in northern Guangzhou providing connectivity to Huadu District. With the line’s opening, the interchange station at Gaozeng on Line 3 has also opened, just one stop from Guangzhou Baiyun International Airport at Airport South.
Finally is the extremely odd Line 14. This serves the catchily-named Sino-Singapore Guangzhou Knowledge City, a new development in north-eastern Guangzhou. Not only does Line 14 not connect with any other lines at present, it is more than 15km from any other part of the network!
Line 14 will eventually connect with Line 2 and Line 3 at Jiahewanggang, but don’t hold your breath.
