As the use of cars and truck freight service increased the railroad industry began to decline. Eventually, the Milwaukee Road filed for bankruptcy in 1980 and closed the Sioux City facility a year later. Thankfully, the city awarded the association a grant to buy the property with the goal of restoring its buildings and preserving its history for future generations. In 2015, the association submitted a nomination form to the National Park Service to add the complex to the National Register of Historic Places. As of late 2016 this designation is yet to be determined.
