The passage under the Wulin Square was built in June 2005, with the eastern side of the passage extending nearly 190 meters and the western side extending about 120 meters.

According to officials with the Hangzhou municipal facilities management center, the renovation project of the passage was launched last November as part of the preparations for the Games.
