Below are the tweets from Alta Alerts about parking availability for Nov. 28 thru Dec. 1. My guess is that things ran reasonably smoothly. That's mostly based on the fact that I can't find articles bemoaning traffic and parking issues, which were readily available in the last few seasons when LCC or BCC roads were clogged with frustrated folks. The commute for people driving from SLC is 5-20 min in the city, plus 20-30 min going up the canyon road if going the speed limit.

Alta opened on Nov. 23. The Alta webpage for parking includes lost of webcams, as well as views of what UDOT is displaying on the lighted signs on the LCC road. Pretty sure that's more info than in the past, but haven't really been looking since I normally stay at Alta Lodge.
