Ohio to Florida on I 75. Steep grades?

The summit, called "High Point", is located just east of Thompsonville in Walker County, Georgia, with an elevation of 2,392 feet above sea level. :C

I took I-65 to I-75 puts you right smack in the middle of it. I think the elevation at that point is less than at the summit but a 7-1/2% grade is nothing to just write off about when driving a MH towing. IMHO, JMHO!

Looks like you cam across 24 from 65 to 75 which would have put you on the steep grade. The OP is coming down 75 and will not be on 24 and will not see the grade which you are referring. The steepest grade 75 has at Jellico is 5% one direction for 5 miles and 4% the other direction.

The two most significant grades I can remember on I-75 is the one climbing up out of the Ohio River valley when you first cross into KY, and it's more sustained than steep (up going south, down coming back north). The other is Jellico just inside the TN border followed by some ups and downs between there and Knoxville, but those aren't bad compared to others I've seen esp out west. From Atlanta south is flat.

Yup it seems like people that live around there AND California people all don't have a problem with that grade!

OP: Google Lookout Mountain for elevation.

I'm from Illinois or what others would call a 'Flat Lander'. :W

Going over a speed bump is the closet thing we have to a road with a steep grade!!:B

I don't know what scared rockhill so bad. I have driven that hill for years in everything from a motorcycle to a tractor trailer. That is NOT a bad hill up or down!

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!

As other have said the only large incline/decline is Jellico pass just as you enter Tennessee heading south. I pull 35' with a GM 6.0 gasser and have no issues holding speed going up or down. Both directions in the steeper portions there are slow truck lanes that you can travel at a slower speed if that makes you more comfortable.

You need to check your geology because it's not downhill to Knoxville or Atlanta. No steep garades.

Good to hear. Thanks for the replies.

We have driven I75 from Cincinnati, Ohio through Atlanta, Georgia, to I-10 and then on to the Panhandle and back again several times. The road is all good. I don't think there is anything excessively steep, grade wise.
