Unlike at 162 you can fit a standard six-ramp parclo AB4 here, i.e. the interchange configuration with which Calgary drivers are most familiar because Stoney and Deerfoot are drenched with them. Not sure why that's not the immediate plan A.

Regardless of perception or what you've seen, a DDI is still way safer overall than a Parclo. Do a conflict point analysis and review the types of collisions present at each interchange type and it becomes obvious. Canadian jurisdictions have been slow to adopt safer road design trends from elsewhere because of a reluctance to ask drivers to adapt to modern design. Even some slow-to-act US DoTs are outpacing us by a wide margin now.
We still get comments that roundabouts are "new" and "scary" from the public despite the fact that the modern roundabout design in North America is over 30 years old and there have been modern roundabouts in Calgary for nearly 20 years. Familiarity shouldn't be a higher-weight value over safety.
I'd willing to bet money that someone will comment on this engagement page that the city should build a cloverleaf interchange at 210th.
