Preferred route, I-80 or I-70 over Rockies?

There are no weather concerns in Wyoming. During winter, the roads are always ice. Regardless of weather.

 

Yeah, and the bloody wind was gusting over 70 today. Glad I'm cutting off on 76 tomorrow...supposed to be even worse.

I'm running this direction all the time, with 80000 gross I'm about half an hour faster from Omaha to Vegas over I-80. My truck is governed to 70 mph, on I-80 there are only a few speed limits (for me). I always go to I-15 thru Provo Canyon, speed limit 55.
Last time I had only 12500 in the box and it was windy in WY, I took I-70 and with this weight I was faster on I-70. It's not only the hills in CO, from Green River to I-15 you have a lot of climbing that costs time.

 

The time to drive 80 vs 70 is not the biggest concern for me, it the condition of the roads. Are you ready to sit two days in Wy for a road closure....or chain up to climb a 11,600 ft hill in the snow?

 

70 hardly closes. If it does not long. 80 can take you awhile if it’s snowing or wind. 70 you have to chain sometimes but you can keep rolling. If I was paid cpm 70 for the win if weather is acting up. If it’s clear weather I’d run 80.
