I pretty much know the route to take is I-75 but here's the deal. I have to drive a trailer from Florida back to Michigan this week and want to bypass Atlanta entirely. So I'm thinking of taking I-95 to I-26 to I-40 back to I-75 in Knoxville and then taking I-75 back to Michigan. I hate driving in Atlanta so I really want to bypass it.
You are adding hundreds of miles to avoid Atlanta.
If you want to avoid the place that much, a better alternative would be:
I-95 NORTH to I-26 in rural South Carolina,
I-26 WEST to I-77 in Columbia, SC,
I-77 NORTH which eventually merges with I-64 at Beckley, WV, remain on I-64 when they split at Charleston, WV,
I-64 WEST to US 35 in Scott Depot, WV,
US 35 NORTH to the Ohio River where US 35 changes to E-W signage,
US 35 WEST to Chillicothe, OH, where US 35, US 50 and US 23 merge, remain on US 23 when they split,
US 23 NORTH to Columbus,
I-270 Columbus Beltway, or OH 315, back to US 23,
US 23 NORTH to OH 15 at Carry, OH,
OH 15 to I-75.
(or, for a slight variation, stay on I-77 at Charleston, then exit onto US 33 at Ravenswood, WV, the take US 33 to Columbus and return to the standard route, a bit more two lane, but less total non-interstate time.)
This route is actually about 45 miles shorter than the default one, although the drive time will be a little longer. It does involve 14 miles of two lane on US 35 in WV, and there are probably 10 to 15 stop lights on the US highway part in Ohio.
