Hello Buraddo,
I extended this residential highway because we can see the left turn arrow sign printed on the street in 2022 Mapillary (https://www.mapillary.com/app/?lat=45.78625069793401&lng=21.236913100002994&z=17&focus=photo&dateFrom=2022-01-01&pKey=2623104394500879) and I did not see any physical barrier preventing this connection in aerial imagery nor in 2022 Mapillary. A bollard is not present in the resources I have available to me but since you have knowledge that says otherwise, I’m happy to defer to your edits. I hope you have a wonderful day!
