The original eastern path of US 66, most of which is currently designated as IL 53, served Gardner, Braceville, Godley, and Braidwood before entering Wilmington. The section of Route 66 from Wilmington to Joliet was added to the National Register of Historic Places on May 5, 2006, and travels through mostly agricultural land, although the area also includes the former Joliet Arsenal. This segment of Route 66 runs through Joliet, Jackson, Wilmington and Florence Townships in Will County. It begins in Wilmington and ends just short of the I-80 interchange in Joliet.
