Hello. Thanks for mapping.
A remark. I noticed that you added a layer to a few roads! Why ?
These roads are not running underground.
If you tried to solve issues which shows up because roads are crossing buildings, solve the issues, rather than hiding them with a layer.
Layers are to be used where rivers crossing roads, where the  bridge gets a layer=1 and a culvert  layer =1
The roof of a petrol station  over a road can be tagged as layer=1>
Best regards and keep mapping
