We've taken 93 all the way up through Nevada, Idaho, Montana and crossing at Roosville. It's a beautiful drive.... in good conditions.
I hope you have contingent plans. Right now, if you enter Montana you have to quarantine for 2 weeks. Canadian borders are closed unless necessary. In reading posts from Alaskans, things aren't going to be open as usual. Denali Nat'l Park - ?? I know it would be an extremely difficult decision to make but please rethink this trip for this year. On a plus side, there won't be a lot of traffic and fuel may be lower. If you're up to boondocking a lot this won't be an issue. Then again, things might change within the next week on a positive side. Good luck!
