"On a mile-for-mile basis, the most valuable major highway is I-75, which runs from Sault Ste. Marie in Michigan’s Upper Peninsula all the way down to the southern reaches of America’s Lower Peninsula, also known as the state of Florida." ($28 million per mile). I used to travel on I-75 frequently and going into the downtown connector in Atlanta where I-75 and I-85 combine is an unpleasant experience with so many cars.
