Greetings Badojo,

Thank you for your mapping in Bosnia and Herzegovina! I recently noticed new highway ref tags, such as ref=R-II 5511 and old_ref=R-457, that were added in this changeset: https://www.openstreetmap.org/changeset/166888058

Do you have any resources that confirm these new ref numbers? Any additional information on these would be greatly appreciated.

Thank you and have a great day!
