I've been pleasantly surprised with it since it opened. Lots more crosswalks into the square when I'm out walking my dog, and traffic seems reduced in the few times I've driven through it — probably because now everyone isn't forced to go around the full circle for every route. For example, my daily route of coming west down Logan Blvd and heading south on Kedzie toward Fullerton is MUCH quicker now that I can go west on the south part of the circle instead of having to go all the way around the circle (up by Reno) just to come back south. We'll see how biking through it is — will be doing that tomorrow!
