This is pretty cool:

Untitled (Pudong, Shanghai) is one in a series of site specific billboards that responds to the proliferation of large scale advertising images upon the urban environment by indexing the social/political relevance of the billboard site itself. Here, images of workers within the barricade replace the commercial billboard. It is at once a testimony to the workers and their role in shaping China’s hyper modern environment as well as an attempt to neutralize the continual commodification of urban space. This project is part of Zendai Museum of Modern Art’s INTRUDE: ART and LIFE series The project was also made possible by the help of: DDM Warehouse Special Thanks: Zhu Tao, Daniel Traub, Sofia Wang and All the Workers of the Himalaya Center’s Construction Site! For more info on the billboard series please visit http://www.mabz.net/BB/MABZ_BB.html

The construction site involved is another Zendai (Big Thumb) project called the Himalaya Center. The best way to see it is to take Line 2 to the Longyang Rd station, cross the road to the north, walk east past the Decathlon and turn left up Fangdian Rd past the New Int'l Expo Center.
