HP123It appears some people have become immune to I-70 traffic. Which is not good. I guess you are forced to if you live on the front range.
Yes there's ways to get around it if you plan accordingly, and wake up at 4 am. Or just don't go on weekends.
If you don't really care about getting that much skiing in, then it'll work for you. But if you plan on skiing alot while you're in boulder, then be prepared to spend half of your time in a car. It's just the reality.
Again, traffic isn't as nearly as some posts in thread are making it seem so I'll chime in again. If I were excited about moving somewhere new to start school and ski a lot, I wouldn't want to be discouraged about something as small as ski traffic before even getting to start the experience.
I-70 traffic is certainly heavy. It's really simple to figure out though, on a Saturday morning get on I-70 (in Golden) before 6. This isn't as bad as it sounds, if you were arriving at the hill a little before 8:30 you would need to be on I-70 around 7 anyway. Sunday mornings are much more random and there tends to be half the traffic.
Eastbound is usually more difficult. There's consistent traffic on Saturday afternoons from 3-6, sometimes later. Sundays are awful. Traffic starts as early 11 am and lasts after 8. Do yourself a favor and never plan to drive between 2 and 5, this is the time when some of the monster delays mentioned earlier are certainly possible.
As I said earlier, the biggest hassle on I-70 are accidents. Whether thousands are rushing to get that sick pow, someone from Missouri is going to Cali, or a semi needs to meet a deadline, snow on the roads causes accidents constantly.
I might have better experience because I'm from Evergreen which is 25 minutes into the mountains, that helps with traffic although it happens to be right where the westbound bottleneck starts too. You'll also notice that this whole description was for the weekend. Traveling Mon-Thurs is a breeze, minor issues Friday.
Blah blah blah enough about that. Welcome to Boulder, I hope you have a great time here and enjoy the shredding. Hit me up if you have any more questions.
