A sad reality of those Perimeter plans is the province wants to down grade Portage (HWY 1) and the Perimeter to a diamond as a cost savings measure.

By making Portage into a diamond the existing bridge decking can be slightly reworked to handle six lanes of through traffic by repurposing the merge/exit lane into a through lane. If they kept it as-is there would be major reworking needed to accommodate six through lanes.
