Hi,

Can you tell me where this object is?
https://www.openstreetmap.org/way/939770064
The layer=-1 tag tells it's 1 level below the Piazza Lauro de Bosis which has not been mapped, only the ways that cross the square carrying that name. Also the area is connected to the ways at the surface i.e layer=0 so I think properly the highway tag of the area has to be removed and place=square to be added+name+surface details and if lit and the layer=-1 tag removed.
                      .
For tagging purposes, the correct tag for highway as an area is area:highway=* See wiki which has no Italian translation https://wiki.openstreetmap.org/wiki/Key:area:highway

Please let me know what that service area is and why it is at layer=-1 as right now it's causing duplicate edge warnings with adjacent pedestrian areas at ground level which a square would not cause.

On the whole, think you inherited these tags from previous mappers going back to 2021, the time being now to correct this.

thanks
