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!
Bennett's Terraqueous Gardens is a high-quality seep that lies at the base of deeply dissected bluffs and hills bordering the east side of the Illinois River. The seep community is usually saturated by groundwater that emanates at or near the base of a hill comprised of glacial till. Narrow spring runs flow in rivulets through the seep. Characteristic herbaceous plants found in the seep include swamp thistle, bottlebrush sedge, spotted Joe-Pye weed, fowl manna grass, swamp goldenrod, skunk cabbage, and marsh marigold.
