Route description
IL 91 serves the cities of Toulon, Wyoming, Princeville, and Dunlap. It travels concurrently with IL 90 around Princeville.
IL 91 does not travel in a straight line between any two major towns. IL 91's endpoints are generally northwest-to-southeast, but the route consists entirely of north–south and east–west stretches.
The Rock Island Trail State Park follows IL 91 for much of its length. This State Park trail is the former right-of-way of a Peoria branch line of the Chicago, Rock Island and Pacific Railroad.
History
SBI Route 91 was the current U.S. Route 150 from Knoxville to Peoria. 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.
