We have to go to Denver for a funeral. My sis has always taken the route to Denver via I-70 thru Grand Junction. I have always driven I-80 thru Cheyenne. In the winter time, I am concerned going over the mountains, won't that take longer to travel, how about the roads. To me the straight shot on I-80 would be best, but I have also been stuck on that road in the winter.
What is the best winter driving road between Salt Lake City to Denver.
