The newly extended Line 9 stretches from the Middle Yaggao Road in the southeastern Pudong New Area to the Songjiang District in southwest Shanghai. The light blue line seen on subway maps bisects the southern part of the main downtown area and services 23 stations along its 40 kilometer track. The line mainly services residents of the southeastern and southwestern areas of the city, but also allows tourists to travel to the suburbs for a quick escape from the city center.
