Line 21 (Shanghai Metro)
Line 21 will be a future subway line on the Shanghai Metro. It will run in a north–south direction through Pudong, connecting Gaohang in Waigaoqiao to the Disney Resort. The first phase will be about long with 10 stations. Stations will have passing loops to allow for express and local stopping patterns.
The line was announced by the Municipal government in 2016. Previous plans in 2014 designated the Disney Resort — Guanglan Road section as Line 24.
