Rockford to McGregor Road Trip: IL to IA Guide

The drive from Rockford, Illinois to McGregor, Iowa covers roughly 120 miles via US-20 W, a route that traces the northern edge of the Driftless Area, a region that escaped glaciation and features rugged bluffs and deep river valleys. This precise geographic quirk gives the journey a surprising topographic drama rarely found in the Midwest.

You'll cross the Mississippi River at Dubuque, entering Iowa on the Julien Dubuque Bridge, a steel arch bridge completed in 1943. The total driving time is about 2 hours and 15 minutes without stops, but the real value lies in the detours.
