311 South Wacker Drive

311 South Wacker Drive is a post-modern 65-story skyscraper located in Chicago, Illinois, and completed in 1990. At 961 feet (293 m) tall, it is the ninth-tallest building in Chicago and the 36th tallest in the United States. It was once the tallest reinforced concrete building in the world. 311 South Wacker was also the tallest building in the world known only by its street address, until it was surpassed in height by New York's 432 Park Avenue in 2015. The lower level of the winter garden was designed for a possible connection via underground passageway to Chicago Union Station. The building also contains three levels of underground parking. The building contains both retail and commercial tenants.
