I got back on 80 and made it all the way to Rock Springs*. In March it got shut down for high winds and I spent a day and a half in Rawlings in October it was spitting snow and sleet and I ended up leaving the highway and taking a back road for a while - 287 I think - which was slower but beautiful and completely deserted. I drove it in late March 2018 and again in mid October 2019, towing a camper both times. Posted by aspersioncast at 9:24 PM on September 1, 2019 Try to time it so that you go through between 11am and 4pm and preemptively plan on just spending the afternoon/evening in Rawlins or Laramie if things go bad. Keep an eye on closures here, and the weather in general, as nickggully says. That said, this is still the route I'd take - it's significantly faster than dealing with the Denver suburbs (which now seem to constitute most of the front range). There have been dozen-car pileups here for as long as I can remember, and the last major one in Spring 2015 was a 70-car pileup. Particularly the truckers - these guys are half-asleep, watching movies, hands off the wheel, and they often don't even notice the cars in front of them in time to brake. It is a particularly dangerous stretch of road, in large part because of the volume of long-haul truckers on 80 every day, poor visibility, and generally weird weather conditions.

It's hard to tell more than a day or two in advance if the pass might close. These storms are not unheard of from late August to June - I've stopped even trying to visit my family from late September to March because of the odds of getting stuck in Denver.

Beautiful weather in wyoming
