Hello, mkarau;
Thank you for contributing to improving OSM maps in the UAE. We understand that you make adjustments based on local knowledge, and we do not change those adjustments, but we fix errors. For example, on this road (way 509050842), it is incorrect for the road to be unconnected to a road network, even if it is under construction. It should be connected to a road network, and you are making it unconnected with this adjustment you made. However, there are other solutions you can implement if this road is no longer operational. You can change its status to `highway=construction` as explained on the Wikipage for roads under construction (https://wiki.openstreetmap.org/wiki/Tag:highway=construction).
If there is a barrier in this part of the road (24.5293531, 54.4189452), you can place it according to its correct type (block, gate, etc.) as explained on the Wikipage for barriers (https://wiki.openstreetmap.org/wiki/Key:barrier). However, the road must also be connected to a road network so that it is not floating. Since it is also incorrect to place a barrier sign at the beginning or end of a road without connecting it to a road network, as I have done here. (node ​​13114224746
node 13179773957). Another solution is that if the route is no longer in use, you can use the `disused highway` tag (https://wiki.openstreetmap.org/wiki/Key:disused:highway). In all these cases, the route must be connected to a road network to avoid any issues on the OSM Map server.
