I agree, 6 lanes aren't really needed past Dougall Parkway or Highway 3.
However, if you're planning on making a sunken highway that will serve long term traffic needs, you may as well make it 6 lanes now. It would be very costly to widen it later and it would also be odd to build it 4 lanes now with room for 6 since that extra lane space is already there.
Next time I'm down in Windsor I plan to give it a drive and give my feedback of this multi-year project. If it's a nice day I may even take some pics and/or video.
