Its termini are planned to be Baoshan Railway Station and Hongjian Road.

It is planned to be 46.2 km (28.7 mi) in length, with 34 stations.

The line hopes to ease car congestion along Pudong South Road, as well as reduce crowding on the southern part of line 8, and the northern sections of lines 1 and 3.

The line was announced by the Municipal government in 2016 and is planned to finish construction between Baoshan Railway Station and Yierba Jinian Road in 2027, and between Zhoujiazui Road and Hongjian Road in 2031.
