Hello. Thanks for mapping here.
A remark. You added a layer-1 tag to a road. Now you tell that that road is under the ground level !??
You probably did it to hide a crossing error with buildings. Just let it cross when the project system does not allow you to adjust or move the buildings.
A validator will correct those issues.
Best regards and keep mapping
