Ann Arbor to Dubuque Road Trip: Scenic Drive Through the Heartland

The drive from Ann Arbor, MI to Dubuque, IA spans approximately 340 miles and takes about 5.5 hours of pure driving time via I-94 W and I-90 W. This route crosses three states and passes through the historic town of Galena, IL, which served as a vital lead mining hub in the 19th century. The path follows the ancient shoreline of glacial Lake Chicago, visible in the flat topography of northern Illinois.

• The most direct route uses I-94 W to I-90 W, bypassing Chicago via the eastern toll road.
• Expect tolls on I-90 in Indiana and Illinois (approx. $15 total with E-ZPass).
• The drive is worth it for the blend of college-town energy, rolling farmland, and Mississippi River bluffs.
