For anyone wondering why the Perimeter was initially built to low standards - go to page 10 of this document:

Dark Grey area of that map is Winnipeg pre-1950, which would basically be the extent of the city when Perimeter was started in 1955. The highway was at least 2 km out from any built-up area of the city at the time. This is also before the car culture boom (and start of city sprawl) of the 60s and 70s so it’s no surprise it was built to rural highway standards and not suburban freeways.
This doesn’t excuse the poor state of things now, but some perspective as to why things were done that way.
