I90 or I80
I have to drive as quickly as possible between Indy and Seattle. I'm wondering which route will have the least liklikhood of snowy roads...I-90 across SD and through Montana or I-80 through Nebraska, Wyoming and up through Boise. Has anyone traveled these routes who can advise me?
This time of year
I have driven both routes a number of times. This time of year, I would suggest I-80.
I just looked at the weather trends over the next 10 days for both routes. It actually looks like more snow chance on I-80, but ground blizzard conditions exist on I-90 even though less snow is predicted. So, I would stick with my I-80 suggestion.
