I was going to say something but looked it up first. I was thinking the OP was referring to what turned out to be I59 South out of Chattanooga which has no long grade hills. Been on I24 a few times with some long grades but don't think we have ever used I75 before except in FLA heading for Tampa area from I10.... North Georgia HIGH COUNTRY has some good mtns there to cross for sure...
