Green Tie Ball is Chicago Gateway Green's signature fundraising event. The infamous gala, returning each year with a new and engaging theme, raises funds for Gateway Green's Expressway Partnership Program. It was first held in 1992 as a 500-person street party and is now one of the best-known charity events in Chicago, and last year was attended by approximately 3,000 people. The gala attracts Chicago's most prominent public, political and media figures, environmental supporters as well as young professionals and local celebrities. With our wonderful partners, volunteers, and strong dedicated following, Green Tie Ball continues to reinvent itself as the most anticipated gala experience of the year.
