Good point. BRT is a good start to improving traffic flow. But the reason roads like Route 90 and Abinoji are so congested is due to the lack of alternative routes. Just like I mentioned that an alternative for Route 90 (like a Waverley extension to Academy), Abinoji Mikanah needs more too. Pembina Highway and the Red River almost feels like a cutoff point for major roads. For example, streets that end at Pembina include Corydon, Grant, Taylor/Stafford, Jubilee, McGillvary, Bison Drive (technically continues, but not a through road, just to serve the U of M). Portage Ave and St Mary's feels a lot like this too. I understand it would cost more to build bridges over the Red or Assiniboine, but a Fermor-Jubilee and a Waverley-McPhillips (at least Waverley North to Academy) would make a difference. More crosstown routes are needed in Winnipeg rather than just ending in random places. Doesn't have to be freeways, but arterials can help do the trick.
Also too, roads like Sterling Lyon are pretty well built, but it's potential is undermined by it ending in the middle of nowhere. Same with Fermor, although it does connect with Dunkirk heading towards downtown, but Osborne isn't meant to be a high-capacity arterial road. Anyways, Sterling Lyon just ends at Waverleyit doesn't really connect anywhere. Jubilee by design doesn't look like a throughfare to me, but plays that role because it's the only way across. That street I would rather shrink and add bike lanes for residential traffic while Wilkes-Fermor could help connect neighbourhoods while moving traffic from one end of the city to the other. Same would go with the Logan-Dugald Connector.
