It turns out that I have only seen the design for the two interchanges through Brandon somewhere else.* Anyway, there's a report titled
Introducing Western Canada Jurisdictions to VE - Manitoba and Saskatchewan by MMM Group from 2011. The 2 options for TCH & Yellowhead Highway interchange are shown on pages 19 & 22. Both redirect Trunk Road 305 to access TCH from another interchange down the road. Let me know if you can still find it.
* On the other hand, it did address select at-grade intersections of TCH by Moose Jaw.
Ps: I guess this will be the unofficial Prairies Highway Thread.
