We just drove up from Chattanooga to Cave City on Wednesday (3/30), we stayed on I-24 all the way till we got to 155 (Briley PKWY) then onto I-65 north. VERY easy route, there's a few stop lights on Briley but we hit most of them right. We drove through there with no troubles at all, it was about 11:00 am when we went through Nashville. We're pulling a 38' fifth wheel.
On a side note not to hi jack this thread but know which cave tour you want to do in advance, we didn't know about the reservations needed to tour (guided) the cave and had to take the self-guided one. Was't what we wanted but that's all that was available at the time. :(
