The Bund Sightseeing Tunnel has a total length of 646.7 meters and is China’s first cross-river artificial sightseeing tunnel. Modern high technologies are applied in the decoration of the interior walls of the tunnel, providing the passengers with background music as well as pictures, patterns and views about people, history, culture, science and technology and natural scenery. The environment-friendly non-driver traction compartments, the whole transparent compartments, and the six-sound-track and high-fidelity stereo system match the changes of the views.
