You can click on the specific segments and it says "estimation year" and "2024 AADT". Any segment with a more recent Estimation year has significantly higher 2024 AADT numbers than nearby segments with older estimation years. That makes me think the model they're using to estimate traffic volumes is inaccurate and there's been more growth in traffic volumes than the model is predicting with old data. There's a ton of segments with estimation years 2014 or older.

The easiest might be to repurpose the current bridge as EB only and build a new WB span to the north of the current bridge.

Agreed, it's a gong show, but unfortunately the Perimeter is so outdated that correcting that problem is a low priority among all the other issues. It would probably only happen when the Red River bridges are up for a rehab, which I have no idea when that might be.

Yep, that's clear, however, traffic count is only one piece of the decision-making puzzle. Collisions, fatalities, strategic importance to the road network also play a role.
See the map MTI shared for the Carberry interchange to argue that it should be a temporary measure and not an interchange, which the politicians ignored. The big coloured circles used some sort of method to determine traffic/collision severity index. St Annes and Dugald are the worst on the Perimeter, even if they have lower traffic counts.

You can cherry pick news articles about a fatality for just about any segment or intersection on the Perimeter. The one you shared is not even recent, but 8 years ago, and the wording indicates the driver lost control of her motorcycle which could be driver experience or roadway conditions that aren't related to the design issues with that interchange. It really isn't clear.
Quickly scanning Google news for articles in the last 4 years, I find deaths at McGillivray (x2 incidents), Dugald, Pipeline, and St Anne's Road intersections, plus between 6 and Rosser and between St Marys/St Annes. This is just glancing at articles, and could be missing some.
The highway has inadequacies all around, and even if it was a perfect freeway there'd still be collisions and deaths. Driver error still happen even under ideal roadway setups.

I'm not advocating for more death and destruction. In fact, I'm hoping our elected politicians chose projects that address the highest risk intersections so that the locations with the highest risk of deaths and severe collisions are addressed first.
