Illinois Route 91 (IL 91) is a rural state route in central Illinois. It runs from the northwest edge of Peoria at U.S. Highway 150 (US 150) to U.S. Highway 34 and Illinois Route 78 south of Kewanee. Illinois 91 is long. Later, IL 30 was rerouted north of Toulon which entirely followed current IL 91. In March 1941, the state announced that IL 91 was replacing the designation of IL 30 from Kewanee to US 150, and has remained so to this day.
