Nothing really to be concerned about. There is bridge construction over the French Broad river before you get to Newport. Traffic has to merge to one lane. It can back up.
Some notes of mine that might help:
I-40 East from Knoxville, TN
I-40, TN, MM 444, Begin 55mph Truck restriction lane.
I-40, TN, MM 445, Caution, 50mph Left curve.
I-40, TN, MM 450, Caution, sharp 45mph left curve.
I-40, NC, MM 20, End Truck restriction lane. 60mph downhill race to Asheville, NC
