With "including the path on the northern end of the light green area" do you really mean the asphalt way connecting Josef Edlinger-Gasse with the bridge heading north, next to the playground?

I guess in that case the path would still exist but needed access restrictions, though when looking at strava heatmap it's still heavily used and sounds unlikely that it can't be used anymore
