You’ll be okay, as long as it’s not actively snowing. It’s plowed pretty well. I used to drive across it every other day in the winter in my shitty little hyundai accent. Only ever had trouble when I got caught in a snowstorm but even then I got across fine.

Oh man it really depends on a lot of factors. I’d say if you want to aim for close to a 100% safe trip then once most of the snow is melted across the state, give it 2-3 more weeks and you’ll likely be fine. I’ve had some trips over the kanc where I didn’t follow that advice and things got a bit dicey around certain corners even at low speeds.
