The Origins of Chicago's Underground

The story of Chicago's underground begins in the late 19th and early 20th centuries, a period of rapid growth and technological advancement for the city. As Chicago transformed into a major industrial and commercial hub, the need for efficient infrastructure became increasingly apparent.
