vid, regarding pembina, its more like the main south->downtown route.
The main north-south (as in context of goes from south of city to north of city) route would be potentially Saint-Annes/Main St and/or Saint-Mary's/Main St through downtown or Lagimodiere Boulevard on the east and route 90 on the west (Kenaston to Century/King Edward to oak pt hwy to brook side boulevard which will also be extended to the perimeter hwy soon)
And yeah U of M is still a ways further south lol
