The main mill operated along a roughly 22-acre lot along the eastern portion of the Chicago River in the Lincoln Park neighborhood for over 112 years before being demolished.[5] The Lincoln Park location was Chicago's oldest steel mill.[6]
In 2006, it bought the site of the former Verson Steel on Chicago's South Side.[7] It was purchased by the Swiss Steel Group in 2008, and has since operated from that location.[8][9]
In 2016, real estate developer Sterling Bay purchased the Lincoln Park site for a sum believed to be over $100 million[10] and renamed the site to Lincoln Yards.[11]
