fracvldXX: Centre-Val de Loire Routes Départementales

[michih]

The M routes in Tours and Orléans are not signed according to 2021 GSV, nor indicated on OSM or GM. I will wait for any confirmation before I will start drafting the systems.

Nothing on OSM nor GM nor 2023 GSV except of M37 and M801 in Tours that are indicated on GM and OSM. OSM was changed in Nov 2023.
wikisara has each kinda route list for Tours and Orléans.
The wikisara route articles indicate

Since 1 January 2018, the part of this road located on the territory of Tours Métropole Val de Loire has been reclassified as a metropolitan road retaining its former name, i.e. M751.

In October 2018, the first 4.8 kilometres of the road south of the Tangentielle d'Orléans were transferred to Orléans Métropole. It was renamed on a metropolitan road while retaining its number, i.e. M97.

Just like Bordeaux (unsigned), Rennes and Rouen. Why "retain M"? "Retain D" would make sense Should I draft them with M or D numbering?

FRA-CVL D206-45 should be FRA-CVL D2060-45.

Numerous M route signs appeared in Tours. Some in 2024, more in 2025 according to GSV. OSM was also updated. I'll split off the fracvlm37 routes later this year.
