For anyone wondering, my post-storm Saturday route up I-77 and I-81 worked well. I came through a few hours after the last of the snow and sleet fell in the area and the sun was out. The interstates were mostly dry with the occasional wet spot that had the potential to freeze up later. Even in the areas that easily had 6-8"+ of fresh snow, I-77 was cleaned up nicely. Between Charlotte and Statesville, I saw a good number of abandoned cars on the shoulders or further off the road, including one that looked to have crashed into a sign, so it was apparently a lot worse earlier. The only small delay we had was a closure of I-77 for an exit because of an earlier accident near Union Grove. Most traffic was using NC 901 to US 21 to US 421, and Google showed lots of traffic trouble along that detour. We decided that our northerner driving experience and an all wheel drive SUV with good snow tires was up for a much shorter detour on county roads between NC 901 and US 421 on the west side of I-77. Even most of those were in reasonably good shape, with the exception of a couple miles that had not been plowed. Nothing that caused us any concern or trouble. The only real slippery travel didn't come until the early morning hours today when we ran into a persistent squall over the Thruway between Schenectady and Amsterdam. I think in the end, this choice of route probably worked a lot better than trying to fight our way up I-95, where the weather lingered much later into the day yesterday. The ride took pretty close to the same amount of time as it normally takes us.
