Ohio to Florida on I 75. Steep grades?

[Buckeye_Chuck]

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?

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!

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.

Interstate 75 all good.... Jellico Mountain, some downhill... but nothing I couldn't handle with a fifthwheel and truck or a motorhome and toad. I can't think more than 6% being on the interstate. KY/TN state line area.

As DownTheAvenue said, all downhill.... lol.

Going from Michigan to Florida, it is all downhill.

There are a few areas. Nothing terrible. As with any steep areas, just downshift, keep it slow and keep to the right lane. There are emergency pullouts, but you shouldn't need to worry about them.

Jellico Mountain as you enter Tennessee, however I did not have any problems the few times I went down it, I did not gear down nor did I need much braking. Nothing bad from the Ohio river through Kentucky. Past Jellico nothing much to mention either. Once you pass Knoxville not a lot of grade the rest of the way. My truck and trailer at the time similar to yours.

My advice is try this google maps for elevation.

It may calculate for 30 seconds.. but pretty cool.
