Ya, I don't know why they didn't make the exit to the mall just after the overpass, and have it just connect to the ring around it. Then you wouldn't have a light and a left turn that backs up to the highway and prevents me from getting to Blue Grass! They could have made the west side of the ring clockwise only with right hand exists to the mall. Keep the left lane free flowing for the most part so that you can get around quickly. Then to exit to Calgary you use the south one, skip the light and just have a right lane back to the highway.
I don't care about Northbound traffic, because they are probably going to Airdrie.
But I'm sure that could be handled with this setup as well, using the north exit. Just means a couple of lefts.
