Ohio to Florida on I 75. Steep grades?

We will be going to Florida via I75. I'm wondering if there are any steep downhill grades,that I may encounter along the trip. Especially in the mountains. Any advise?

don't know which route you are taking but......

Stay AWAY from Chattanooga!!

Coming down from Wisconsin I came thru Chattanooga and it is a straight shot straight down. And I mean REAL far down.

I didn't know this and was in wrong lane when I reached the top and saw what I was in for. No one would let me move over. I thought I was going to die!

Found out later it is a 7-1/2% grade.

After that first newbie trip with my MH that day....I now know what those yellow signs with a picture of a truck on an angle mean AND what the 'numbers' under the truck mean! :B

After that experience when I was Snowbirding South I took another route down. Didn't care how many more miles more it was to go around. I was NEVER going down that road in Chattanooga ever again.

Check your route map to see if it includes what I now call the Chattanooga drop off!
