USX – Chicago Park District

Park 566, also known as “USX,” is a former steel mill that operated for more than 100 years as part of US Steel’s South Works facility. Having been demolished in the late 1900s, the 68.2 acre space is now undergoing a major restoration process that includes controlled burns, mowing, and installing native plants suitable for prairie and savanna habitats. The resulting natural area will provide wildlife habitat and a place for people to explore and enjoy nature along Chicago’s southern lakefront.
