Hi there, I know it's been a while but just letting you know that the 'service' tag is often unsuitable for service roads like the ones tagged in this changeset. It's a bit confusing given the name, but what we commonly call service roads are better known as "access roads" since they provide access to properties off the main carriageway. The access road should be tagged according to its function, which in this case is still 'primary' since the access road still carries high volumes of through traffic and doesn't carry significantly less traffic than the inner carriageways.
