Illinois Route 47 (IL 47) is a 169.76-mile-long (273.20 km) largely rural north–south state highway that runs from the Wisconsin state border at Highway 120 near Hebron, to IL 10, just south of Interstate 72 (I-72) near Seymour. IL 47 is in primarily rural areas but in several suburbs of Chicago, such as Woodstock and Huntley, traffic can be heavily congested.

Interstate 72 (I-72) is an Interstate Highway in the midwestern United States. Its western terminus is in Hannibal, Missouri, at an intersection with U.S. Route 61 (US 61); its eastern terminus is at Country Fair Drive in Champaign, Illinois. The route runs through the major cities of Decatur, Illinois, and Springfield, Illinois. In 2006, the Illinois General Assembly dedicated all of I-72 as Purple Heart Memorial Highway. The stretch between Springfield and Decatur is also called Penny Severns Memorial Expressway, and the section between mile 35 and the Mississippi River is known as the Free Frank McWorter Historic Highway.
