The more I think about it, the more I change my mind. All options are 6 lanes by the way, which shouldn't be overlooked.
In options 1-4 they have Archibald as the major, Dugald as the minor. As shown on that image. Seems it should be the other way, as Dugald would have more potential for higher speeds. Looks like it could fit there.
But at the same time, there's lights on Dugald anyways. No lights on Archibald anywhere close, so it's good in that sense. Archibald actually has potential from Fermor, only two lights.
Then again, put the interchange at Lag as an overpass. Normal diamond or whatever. That would be amazing. It would clear up that whole stretch of Lag. Build the underpass at CPR Emerson with Archibald and Dugald as an intersection, like it basically is now. Improves that area quite a bit. Almost the best of both worlds.
Interesting in option 5, there is no residential demolition east of the river. I always thought they would be completely gone in that scenario. I also like how option 5 is an overpass. So if I had to choose, it'd be option 3 still since it's completely separated from the rail. Option 5 has that stupid ramp at grade, otherwise I'd pick 5.
