Native Cincinnatian and retired Actuary (math freak) here. As part of a project we found that Greater Cincinnati is the population center of the country. Cincinnati itself isn't that large population-wise, but countrywide there are roughly the same number of people living north, south, east and west of us. As a consequence, I-71, I-75 and I-74 go thru Cincinnati and are tied together by I-275, often called the circle freeway.
So the answer is its busy, and a lot of the traffic is big semis. The weight of the semis turns cracks into holes. Cincinnati only has two seasons. Winter and Construction.
If you have kids, you can keep them busy writing down the state names on the different license plates or counting orange barrels. :)
