Gas prices along the route tend to be slightly lower in Michigan than in Wisconsin, so consider filling up before crossing the border. The Mackinac Bridge toll is $4.00 for cars, payable at the northern end.

Road conditions are generally excellent, with smooth pavement and clear signage. However, winter driving can be treacherous due to lake-effect snow, especially near the coasts. Always check weather alerts before departing.
