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?

Steep grades pretty much doable if you go slow. Speaking of SLOW, you will encounter a lot of that as you approach Atlanta in morning traffic. 😉

Jaycocamprs,
I should have said NEAR Lookout Mountain. Thanks for the correction.

Born in Ohio & live in Miami, Fl. Done the trip many times before I realized a much better route. We always go from Ohio down Rt 35 to W. Virginia, W.Vir.Turnpike, I-77, I-26 to I95 all way to/thru Florida.
Much prettier scenery, much less traffic, Miss Dayton, Cinci, ATlanta & all those trucks going 80 mph. Try it, you'll never go back to I75.:B


How are the downhill grades. I remember going that way years ago in a car. I seem to remember being in some high elavations.

Last fall I encountered Lookout Mountain on my way from Nashville to Atlanta. If I remember it was a 6% downhill grade for 4 miles. I downshifted to 2nd gear to enable me to stay at 55mph with little or no breaking.My 6.2 gasser was reving at 5,000 Rpm. The red line is 6,000 rpm. I'm hoping not to encounter that steep a grade on I 75.

Nothing like Monteagle. Not quite as steep, and in steps. Also much straighter

Relax and ride. Not too bad. Make it to Cartersville KOA and call it a night.

I always used the KOA at Cartersville GA or Corbin KY for overnights in both directions. Both are nice and close enough to the intersate for convenience and far enough for quiet at night for sleep.

I got off I-75 at Cleveland and took the Dalton Bypass, going nowhere near Chattanooga, and the got back on I-75 near Dalton. No great excitement, mostly a nice country drive.

Rockhillmanor is describing I-24 at Monteagle west of Chattanooga, which can elevate your pucker factor.

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.

Lookout Mountain
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.

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
