Fuel and Route Economics

Fuel prices vary along the route. Missouri and Illinois tend to have lower gas taxes than Wisconsin and Minnesota. Fill up before crossing into the Twin Cities metro area for a better rate. Expect fuel costs around $60-$80 for a typical sedan, depending on your vehicle's efficiency.
