1 Introduction In order to meet the needs of reform and opening up and the development of Pudong, the Shanghai municipal government decided to build a double-track tunnel south of Yan’an East Road Tunnel. The middle section of the two tunnels are basically parallel to each other. The south tunnel of the original fork-lift tunnel of Puxi Taikou and the Yan’an East Road is connected to the second tunnel of the double-track tunnel. The Lujiazui Road of Pudong and the original tunnel lead-way merge directly with Lujiazui Road. After the completion of the double-track tunnel, the Yan’an East Road Tunnel will become a double-lane, four-lane tunnel in which vehicles travel in the same direction. Double-track tunnel full-length 2207.498m.
