text: There does not seem to be any difference in the road layout between official maps and OSM. A survey might be needed to map any recent changes, but in absence of this OSM matching official maps should be good enough. Obviously this note has been laying unattended for 6 months - which is why it is important to be precise in describing the problem while you have the information fresh in your memory. :)
