this part of the path is not reachable, there is a barbed wire fence at the T-intersection towards this direction

This fork is currently problematic when using the navigation: if you're coming from the north and are supposed to stay on the 80, there is no announcement to "keep right" or "use right lanes". normally this works correctly for forks like this. OSM seems to think that going onto the 57 requires action and staying on 80 does not but that isn't the case...
