We drive from Sw Wisconsin every year, this year lucky to be going down twice. Oct, and jan 1. Illinois is mostly 65, and closely watched. We go through Rockford, Bloomington/Normal, Champaign, down to Effingham, to Paducah. Lots of radar between Bloomington, to champaign. Heading south of there is a quieter Long, LONG drive. We pull a 5th wheel, and go 65 as we don't want to contribute to the land of "Bears" fans! The one irritant is how fast and early rest areas fill up for a stop and shut eye. We purchased the app All Stays that gives you free rest areas, etc, along the way, as well as wal marts, ask to park, cracker barrels that will let you stay. Have a safe trip, and enjoy.[/QUOTE
The reason I ask the question is I recall seeing signs that say truck spped limit 55 - I also recall something about cars with trailers at 55 too. We will take the same route you suggest - we are going to try to make it past Nashville on the first day and stop for a short nights rest and then head to st Augustine for a couple of days. We have made the trip a couple of times. My other option is to go down through Iowa and then through St Louis on to Paducah. The mileage is about the same but there is about three hundrd miles that are not interstate but two lane highway.
