Hello. Thanks for mapping on this task.
A few remarks about mapping and tagging of highways.
A: Tracks never connect roads with houses .Use path narrower than 2 mtr.
unclassified for other roads
service, where a single road only gives access to a farm, building or factory/quarry
In rural areas, the tag residential is not to be used.
Please read the highway wiki. Link in the instructions.
Best regards and keep mapping
