Recently, a massive air corridor is under construction to connect four 250-meter-high skyscrapers in southwest China's Chongqing Municipality. The Raffles City Chongqing project is near completion and should open later this year. 

Dubbed an engineering marvel, the Raffles City Chongqing project is designed by the famous architect Moshe Safdie and consists of a collection of eight towers and a enormous 300-meter-long sky bridge. 

The buildings are situated in the center of Chongqing, facing the intersection of the Yangtze River and Jialing River. 

The Raffles City Chongqing complex will also include a 230,000-square-meter shopping mall, 1,400 residential apartments, a luxury hotel and 160,000 square meters of office space.
