Sioux Falls to Bloomington Road Trip: Hidden Gems on I-90 and I-39

Unknown to many, the 440-mile stretch from Sioux Falls, SD to Bloomington, IL traces the edge of the 19th-century Big Sioux River fur trade. The route follows I-90 East then I-35 South, merging onto I-39 near Rockford. Total drive time averages 7 hours without stops, but the real journey lies in the detours.

This corridor cuts through the Mississippi River's western watershed, offering a rare blend of prairie potholes and glacial moraines. For those wondering is it worth driving Sioux Falls, SD to Bloomington, IL, the answer is an emphatic yes if you value solitude and agricultural grandeur.
