Hello! I am seeking some advice. I have done a few cross country trips, but only in the Spring and Summer. I am looking to drive from Chigaco to Portland in about two weeks. Is there a safe way to go across the Rockies?

I will be driving a little Honda Civic Hatchback.

I've seen that most people advise taking I90 because of the lower elevation. I am wondering if it will be very slow going because of the weather. I have about 6 days to make the trip.

Any advice, tips, anything would be helpful! Thanks
