Since Shanghai Metro Line 9 opened last year, the stretch from Guilin Road to Yishan Road has been served only by a shuttle bus.
No more: as of 28 December 2008, you can now take a Line 9 metro train directly to/from Yishan Road, where you can interchange with Line 3 and Line 4.
The Explore Shanghai metro map has been updated to show this new connection. If you drag between two stations to plot a route, you’ll now see the new faster times.
Update January 2010 Line 9 was extended to Century Avenue in Pudong
