First, that dreamscape shit is total BS. They want to raise awareness about it. Completely pie in the sky, not going to happen, type of shit. I want to build the tallest tower in the world, right here in downtown Winnipeg. Let's talk. That's the kind of thing that is.
The Google Maps location is Sage Creek. Theres houses planned for that land. And the Bishop extension goes right along the power lines to at least Plessis. Then it's outside CoW control. The route beyond that is undefined, but is supposed to connect with Plessis underpass basically. There's a future route through the golf course. I believe the inner ring road study slated for a couple years will be sorting this sort of thing out. Dawson would be re-aligned to connect with the Fermor access point already there for the north side.
Maybe they were talking general area. Maybe east of Plessis. I don't know.
The land behind Southland Park is indeed slated for development. Not sure about Costco, but it's going to be mostly houses, with some commercial along Fermor IIRC. The development name is something like Dawson Trails and has been in front of the City for re-zoning, etc. The land has been cleared of all trees a year or two ago.
This thing. I think they're only doing the part north of Dawson right now.

Edit: To add, if anyones curious or noticed it. Bishop is built on the detour alignment where it connects to Lag. If there were ever to be an overpass built, it would go north of the Bishop/Lag intersection. It would basically straighten out Bishop from Boul De La signeueurueureurueueurur to Lag.
