The Riverside Plaza is an Art Deco style building at 2 North Riverside Plaza in Chicago, Illinois, United States. It was originally known as the Chicago Daily News Building. At the time of its completion in 1929, the Daily News was one of the dominant newspapers in Chicago. The first building in the United States to develop the "air-rights" over railroad tracks, the 26-story building helped revitalize the south central Chicago River from industrial transport to urban office corridor and made innovations in engineering and urban design.
