Roads in Pudong have no particular longitudinal or latitudinal orientation. Major thoroughfares Pudong Avenue, Zhangyang Road and Yanggao Road run east–west until Yangpu Bridge before turning gradually to become north–south. Century Avenue crosses all three major roads and extends from Lujiazui to Century Park. Yanggao Road extends south to the A20, Shanghai's outer Ring road, which runs east–west from Xupu Bridge and then north–south beginning at the interchange near Renxi Village, when the east–west expressway turns into Yingbin Avenue, headed for Pudong International Airport.
