Remnants of the old United States Steel Corporation South Works manufacturing mill remain in Steelworkers Park on March. 2, 2021, in Chicago. The mill, which once employed thousands of people and served as a lifeblood for the neighborhoods around it, closed in 1992. All that remains of the demolished mill are unused rail lines and massive concrete walls, roughly 30 feet high and 2,000 feet long. (Erin Hooley / Chicago Tribune)
