Duluth to Le Claire Road Trip: Epic Mississippi River Drive

The route from Duluth, Minnesota to Le Claire, Iowa follows roughly 330 miles of US Highway 61 and Interstates 35 and 80, stitching together Lake Superior's shore with the Mississippi River's first major bends. This drive passes through the birthplace of the Mississippi River at Lake Itasca's headwaters (a slight detour) and traces the river's nascent path through bluffs and farmlands.

US-61 is the backbone, a two-lane highway hugging the Mississippi River north of La Crosse. South of La Crosse, I-35 and then I-80 offer faster travel. Gas stations are abundant in towns like Red Wing, Winona, and La Crosse, but sparse between small hamlets. Plan fuel stops every 100–120 miles.

• Estimated fuel cost (gasoline): ~$55–65 (SUV) at $3.50/gal
• Rest areas: Well-maintained state rest areas every 30–50 miles on interstates
• Tolls: None on this route
• Road quality: Good to excellent; US-61 can be winding in the bluffs
