Primary Highways and Roads

The main arteries are I-35 North from Kansas City through Iowa, then I-35/I-80 East to US-218 North, and finally I-94 East into Eau Claire. This route is well-maintained, mostly four-lane divided highway. An alternative is to take US-36 East to Hannibal, then US-61 North, but that adds time.

• Des Moines, IA to Eau Claire, WI: I-35 North to US-218 (via I-380), then I-94 East. About 330 miles, 5.5 hours.

Fuel and Route Economics

Natural Landscapes and Attractions

From the rolling plains of Missouri to the driftless region of Wisconsin, the scenery transitions dramatically. Near Cameron, MO, the flat farmland suddenly gives way to wooded hills. In Iowa, the Des Moines River valley offers a scenic corridor. Approaching Wisconsin, the landscape becomes hilly with limestone bluffs and dense hardwood forests.

Local diners and Iowa meat-and-potatoes define the food stops. In Des Moines, try the taco trucks on University Avenue. In Eau Claire, the culinary scene focuses on farm-to-table and craft beer. The route lacks fine dining but excels in comfort food.
