Tunnel under Huangpu river
October-November 2008

There is a tourist tunnel between the Wai Tan (The Bund) embankment and Pudong district under the Huangpu river. One way ticket will cost you 30 yuans ($4.5 USD), return - 40. I don't think that anybody buys a return ticket for 40 yuans. Even children would not like to see it twice. Those who want may follow the link and watch a video from the tunnel.
