We'd be traveling from the Ann Arbor area of Michigan to Bar Harbor, Maine, during the summer of 2020 or 2021. Although the tollways are easy travel, they tend to be very expensive when you have a 40' DP towing a truck.
Is there an alternative route that would still be freeway (not all the little towns and stoplights!) but not be toll? Maybe more scenic? But still have truck stops for diesel?
