SPUIs and divergent diamonds ftw. People will be able to navigate it just fine with proper signage. The only thing is trying to get over the fact that you're in the left lane, though even that can probably be mitigated with a higher wall between the lanes.
As for SPUIs, the only one I know of in Calgary is at 14th St. and John Laurie. But that thing seems to have been working great for years. Are there any others in town?
