Hey! Yes I get notification emails, thanks for the quick reply!

It's great that you follow the construction site and map the progress, my only issue is that even during construction bicycle traffic was (probably?) still possible. I went there yesterday cycling into Rebhanngasse is allowed (they put up a temporary sign).

I guess there is not a single opinon regarding this topic in the community, but I just wanted to sensitise you to try not to break existing routing.
