The current highway 7 link is also an area marked for high growth over the next few decades. So we'll need a lot more capacity than we already need.
Right now there's relatively little 'local' traffic along the route. It's mostly people starting in KW and ending in Guelph (or vice versa). That's beginning to change and will continue to change. Meaning supporting things like pedestrians/bikers/public transportation will become more and more important. And these things don't play nicely with a large group of people that just want to get from one end to the other as fast as possible.
