I don't think the highway will ultimately improve traffic and much to Ford's dismay I really don't see "solving traffic" as the reason it (or most highway projects) should be built in the first place. What it will do is increase capacity, create new connections, and take trucks off roads. If Brampton plays it right, they can narrow lanes like Toronto and create safer streets. In general highways + smaller arterials are a much better idea than endless 7 lane stroads that make up most of Peel Region. That's why the whole boulevard monstrosity was never a good consideration in the first place.
