The route from Chicago, Illinois to Madison, Wisconsin spans approximately 150 miles (241 km) via I-90 W and I-39 N/US-51 N, typically taking 2.5 to 3 hours without traffic. This corridor was once part of the ancient Glacial Lake Wisconsin basin, which shaped the rolling hills and fertile plains you'll traverse.

Major exits include Beloit (exit 185) for Janesville and Madison. Toll roads are present; the Chicago Skyway segment is a toll road, so have cash or an I-Pass.
