It's gonna be waaaaaaay worse.
Before I actually saw the bypass I thought I would have to avoid I-70 at all costs this summer. It sounded like the worst traffic nightmare imaginable.
Having driven through the bypass I have to say, I'm impressed. They engineered a pretty decent solution to closing down the tunnels. I may be eating my words later this summer but I think traffic is going to be only moderately worse than it would have been otherwise.
I try to be a glass half full kind of guy.
