We did a lot of that in the opposite direction back in 2012 - I-70 to I-68 to I-79 back to I-70. Had no trouble at all, until we hit the intersection of I-70 and I-77 around Cambridge, OH, and were in a full-stop, move three feet every five minutes traffic snarl - due to the construction. I'd hope they'd be finished THAT by now, but that was the only rough part. East of there was just fine.
I-68 in western Maryland is a nice ride, I'll say that.
I do not know I-79 up to Morgantown, but I've done I-81 down along the spine of Virginia, and it was a nice ride too. When we came back east from the SLC trip, we took I-64 from St Louis all the way to Norfolk, and the area around Charleston was rough - a lot of construction, and we hit town about 9:30 on a Thursday night. It may be done by now. We stopped for the night in Beckley, but obviously if you head north on I-79 you'll make that turn in Charleston.
Always remember, you're a unique individual - just like the other 7 billion people on the planet...
