I've always been a fan of roundabouts but this one isn't as good as it could be. The merge zones are way too short, curbs almost intrude to the point that if you're forced to make a line correction because someone else screwed up you'll probably hit the curb and the lanes are borderline too narrow if towing a long trailer like so many contractors do. I've always enjoyed the goat path but take 403 as often as not now because most people are too stupid to handle the new layout.
