Lexington, KY to McGregor, IA: A Journey Through the Heartland

Did you know that the route from Lexington, KY to McGregor, IA roughly follows the boundary of the Illinoisan glaciation, leaving behind fertile loess soils that define the landscapes of Indiana, Illinois, and Iowa? This 650-mile drive takes you from the Bluegrass Region's limestone-rich horse pastures to the driftless area's rugged bluffs overlooking the Mississippi River. The trip typically requires about 10–11 hours of driving time via I-65 N, I-74 W, I-80 W, and US-18/IA-76.
