The Chicago Loop Alliance, formerly known as the State Street Council and the Greater State Street Council, was founded in 1929 to promote the business interests of downtown State Street. This collection documents the activities of the organization and is particularly rich in information about the State Street Mall, when State Street was closed to vehicular traffic between 1979 and 1996. The audio/visual component of the collection shows changes on State Street, and around the Loop in general, throughout the 20th century. [Finding aid]
