Not sure where in Nashville you are leaving from. We departed from near the Opry Monday morning heading south on 65 around 1000 and had no problem, but we were not trying to get on 24.
Came in Friday from Indianapolis on 65 and again had no trouble getting to Opry area, but we're not near 24.
On Sunday we had a devil of a time around downtown due to the closures.
We came from Colorado, but by way of Iowa to have slide repaired at HWH. You would not want to take our route just to dodge the closures in Nashville.
Have a great trip and enjoy Colorado. We sure did.
