The boundary I took care of yesterday. Ideally roads are not used as members of boundaries as that frequently results in breaking those when mappers work on the roads with boundary relations associated with them.

Unfortunately Via Tiburtina still has the service road and your new tertiary on top of each other. Laurenziano is fine, but I don't understand how that one changed from oneway to bi-directional. You need to confirm that as it has major routing implication.
