I took a moment to find the interchange. It appears to be the 285/75 interchange [1]. Eyeballing it based on the scale in Google maps, if you zoom out until you see Atlanta itself... and it takes quite a few zoom levels... it looks to be 12-15 miles from the Downtown Atlanta you'd be concerned about, or, in terms more relevant to the current discussion, approximately 20 Florences laid end to end.

The numbers are quite approximate, but the orders of magnitude are definitely correct.

Several of the Florences that would be laid end-to-end to get to Atlanta as the crow flies appear to be going in places that have virtually nothing there and could actually go there. I can't tell from Google maps if perhaps that's all swampland or something, but a lot of it isn't utilized, regardless of the reason.

If you want to make the point that cities should be more walkable or whatever, this is a terrible hook to do so with, because the existence of large interchanges has nothing to do with the cities not being more walkable. These large interchanges, in general, do not exist in downtown areas, and if you still complain about them it starts to sound more like you have no idea how large the world is. It comes off less like trenchant criticism and more like Puritan-style "those damned car owners are having fun and they should be stopped!".
