Fog is one problem. Wind is another. You should try it under a wind advisory. The majority of the incline was blasted out of granite on a steep mountain on the front edge of the escarpment, going from essentially high plateau to mountain pass, rapid descent and then Piedmont below in NC. The weather changes, so fog or wind are frequent. Not unusual at all to see semis blown over onto their sides. Really pretty view to the southwest along the front of the Blue Ridge down into NC coming out of the gap, though. I like driving it in good weather. I avoid it in bad.
I know well.
Heck, I used to drive it when it was 52. Talk about wrecks.
Really crooked, narrow, steep steep steep.
Trucks would burn out their brakes and off the mountain they would go. I would see one off the mountain almost every time I drove it.
I have been on I 25 around Albuquerque In real bad winds. There is a real bad stretch about 40 miles south of Albuquerque where the highway goes through several canyons. The NM highway department even has wind socks installed there. I was traveling through there on a real windy day. A mini van passed me going very fast. I came across the van upside down on fire in the median about 10 miles down the road. You have to drive for the conditions. Traffic was going about 45 MPH and that was dicey.
