I was pleased to notice that the updated boards from the May 9th open house have been posted to the Crowchild project page. I don't envy the job of the folks who had to find a way to detour the north pathway during it's busiest months. From the posted boards it's not clear what mitigations they have been able to work in to help out with crossing Crowchild Trail at rush hour and how small the islands will be and if it will be a proper multi-use crossing instead of a crosswalk.
It's not going to be a fun detour but the goal as I was told at the open house is to get the Crowchild bridge open again before these closures for flood mitigation and stormwater outflow lifecycling go into place.
Hopefully to help clarify the map from what I got from the open house:
The south section is a continuation of last year's work where they took out the concrete structure. They'll be putting in the wood lattice work like seen further up river.
The west section is in broken up into two pieces (purple and red) - the goal being to finish the purple section first to allow everyone to get to the new signalized 25th St crossing for the rest of the construction period.
The east section across from the old CBC building will result in a new pathway once the stormwater outflow work is done.
Please feel free to correct anything I may have got wrong :-)
