Hello, mkarau;
I want to thank you for your contribution to improving OSM maps.
I noticed that you placed a block at the end of a road and another on a road under construction (n13114224746, n13179773957).
I wanted to clarify that we are making these changes according to the rules stated on the website OSM Wiki.
Regarding my specific case of placing a barrier at the end of an intersection, according to the OSM Wiki website (https://wiki.openstreetmap.org/wiki/Key:barrier), it is incorrect, as a barrier is not placed at the end of a road or at an intersection of two roads. As for the case of placing a barrier on a road under construction, it is meaningless because the road is under construction and therefore inoperable; placing the barrier does not add anything new.
We also make these changes based on recent satellite images and include their dates in the source.
We have no problem making any changes based on local knowledge or survey, but we make modifications that are consistent with OSM policy.
Regards
