This was unfortunate because they blocked the sign that said the canyon was closed due to weather, the whole time people were passing the snowplows to get ahead, (which was stupid in my opinion). Once the snowplows turned off the highway we were able to go over 25 MPH through the canyon but were unable to go more then 40 MPH. Char got to drive through the worst of it all. After we got through canyon I-15 was nothing compared to sardine, but we still kept our distance due to other people not having their snow legs yet. We got to our appointment, headed back up to Logan, and thought the roads at 9:30am had improved a ton compared to 5:30 that morning. Once we got to work, everyone was saying that the canyon was closed all morning and should re open later in the day.
The worst time through the canyon was on Christmas Eve 2008. We went down to spend some time with our families at the last moment when we were able to get time off. The way down was okay, a bit snowy but all right. On the way back up it was getting more and more snowy until we got to Sardine. At the time we were in a older car (about 10 years old, totaled a couple times, almost 200K miles and bad tires) but we were not about to turn back, had no where to stay so we decided to press on, pray hard, and trust in the Lord to protect us. On the way up cars were skidding off the road and we couldn't see further then a couple car lengths in front of us, the lines were all but invisible. It was miracle that we were able to get through the storm and safely home without a dent.
I wouldn't recommend it-unless you really feel like testing your nerves -or you don't notice those road closed signs by accident…..
