gufn was activated on 2016-03-31. gufd was promoted to preview on 2019-08-26. Wikipedia reports about a 2018 change for national roads but it was only edited in 2021. For instance, N3+N4 seem to be departement roads now: RN3 to Dégrad des Cannes, the main harbour, and RN4 to Cayenne – Félix Eboué Airport became departmental routes in 2007, and merely retain the name.
It was a 20
08 change, with a supplimental change in 2016 when the Collectivité Territoriale was created. That's a general DOM-TOM thing whereby National Government has dropped almost all overseas N roads and handed them over to the departments. Signs are still red cartouches and so there's no easy way of knowing that N3 is a different system to N1. And as we have a separate gufn system rather than having them as part of fran, it is already ambiguous as to whether this a national system dealt with in Paris, or a regional system deal with in Cayenne...
The Collectivité Territoriale government of Guyana consider the N1-N4 (and only them) as primary roads.
N5:
Seems to be D11 now, see OSM, GM and wikipedia D route list
OSM has it as 'RN' and 'N3'. GM as nothing (and routed closer to the Maroni river). Both, and Wikipedia and Wikisara have D11 terminating at Saint-Jean-du-Maroni.
https://carto.geoguyane.fr/1/Observatoire_economie.map has it as a secondary route numbered 'NC' (same as with the N2001 Kourou).
Wikisara says, of this road
"It was built from 2004 by the Guyana Region , which is the contracting authority. This institution is not empowered to manage roads and has therefore planned to classify this axis as RN5 . Its status and precise numbering remain unknown to this day even though it is now managed by the Territorial Collectivity of Guyana ."Deleting, but keeping file
N2001 (Sinnamary):Does it exist? It's fully concurrent to D21 right now!
It's D21.
That leaves N2001 (Kourou). Deleting and keeping file on that.
