I80 Wyoming

Between SLC and where? Cheyenne and SLC? that's a 6 hr run, very doable. If the steering wheel holders and buffoons can keep it out of the ditches or from banging into each other, Wyo. will keep the road open all the time, they don't usually start closing it until the accidents happen. Except Sherman, it can ice up pretty quick and they will shut it. I've seen stretches of 80 between Rawlins and Rock Springs where the the max speed was 25 mph because of ice and the road stayed open....that was a fun ride....5 hrs from Rawlins to Rock Springs.
