Expansion of the Future. Dayton's Beltway.

Beltway, circle freeway,... the loop,.... whatever you want to call it in most big cities,.... Dayton has half or quarter of one.  And that would make sense.  It's an important region, however it is a mid-sized city.  I-675 is basically a shortcut for those heading northbound on 75 to 70 (I-70 East).

What it looks like now, and what it might look like in the future.

Just some loosey goosey imagination of burgeoning suburbia Ohio.  Freedumb of thought.
In the illustrated case, Tipp City, Brookville, New Lebanon and Germantown would house the boom.  Perhaps the circle should be wider,....stretching more above Tipp City to Troy (or in between), and more towards Lewisburg, West Alexandria and Gratis.  Some large cities have rings of loops.

Of course these 'daze infrastructure upkeep and improvements are needed as the stimulus, and not some built-it-they-will-come stimulus that would also require more taxes and upkeep, but it's head in the clouds and a hundred years from now.
