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:
Quote
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.

N5:
Seems to be D11 now, see OSM, GM and wikipedia D route list


N2001 (Sinnamary):
Does it exist? It's fully concurrent to D21 right now! It's indicated on GM but not on OSM nor signed at N1.

Il semblerait que la RN2001 (973) corresponde aussi à un délaissé de la RN1 (973) dans la traversée de Sinnamary depuis 1999.
What do "semblerait" and "délaissé" mean in this context? Is it just wild guess?


Please check the N routes first. I'll peer-review the D routes subsequently.


Edit: délaissé -> semblerait

It was a 2008 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.

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

It's D21.

That leaves N2001 (Kourou). Deleting and keeping file on that.
