More concrete plans have been released about how exactly Shanghai will be connected by subway to Suzhou, its neighbor only 100km away to the west.
The Suzhou city government published plans this week showing that Suzhou Metro Line 4 will be linked with Shanghai Metro Line 17 sometime in the future. Currently, Shanghai’s Line 17 is under-construction. When it’s finished it will connect Hongqiao Railway Station with Oriental Land theme park in the west. Apparently, it will also need to extend out a bit farther before linking with Suzhou’s metro, like so:
But that’s not the only one you can get to Suzhou by subway. Eventually, Suzhou’s S1 line will be extended all the way to Huaqiao Station (花桥) in the satellite city of Kunshan, at the very end of Shanghai’s Line 11.
To hopefully make that all a bit less confusing. Here’s a map of what Shanghai’s metro system will look like in 2020:
By that time, Shanghai will have added four new metro lines, so you’ll never again be more than 600 meters away from a station.
Alternatively, you could always just take a high-speed train to Suzhou from Shanghai Railway Station or Shanghai Hongqiao Railway Station. It takes like 30 minutes.
