Where is the Illinois River Road?
Traversing both east and west sides of the Illinois River from Ottawa, 150 miles south to Havana, the Illinois River Road has spurs to the communities of Princeton and Canton. The Illinois River Road corridor has over 100 natural and historic sites and numerous unique communities located throughout its 10-county region.
The Scenic Byway is conveniently located between Chicago and St. Louis, but just far enough to get away from it all. So get off the beaten path and see what the Illinois River Road has in store for you!
Old Indian Boundary Line Prairie State Route 26, Princeton, IL 61356
Established in 1816, Illinois' Old Indian Boundary Line ran from the southern tip of Lake Michigan down to the Rock River's confluence with the Mississippi River. In 1982, a decision was made to restore a 7-acre parcel of land along SR 26 back to native tallgrass prairie habitat. Today, the site has matured beautifully and is dominated by a lush, healthy stand of big bluestem grass with an accompanying mix of mountain mint, coneflowers, sunflowers, asters and other prairie wildflowers.
