fragesdXX: Grand-Est Routes Départementales

[michih]

This might be a GO for drafting the system

No
First, M1 in Saint-Julien-lès-Metz was signed in September 2024. OSM + wikimetz indicated that there is a M1. D2 in Saint-Julien-lès-Metz is still indicates as D2 on OSM. D2 is not mentioned on wikimetz. M3 in Saint-Julien-lès-Metz is indicated as M3 on OSM but also not mentioned on wikimetz. August 2023 GSV does still indicate D2 and D3. All examples are in the same community and should thus all be M or D.
Second, Woippy belongs to the metropolis but OSM changes from M to D routes at the Metz city - Woippy community boundaries.

I need to wait for better evidence what routes have been changed, and what communities have M routes now. I should likely wait for 2024+ GSV coverage.

I've traveled M999, M955, M4, M603 and M954 in the east of the Metz metropolis today. All routes outside of Metz are perfectly signed with blue M numbering. km posts are still yellow with D numberings. Intersecting routes are also signed with blue Ms. Back in 2023 (latest GSV), everything was still in yellow D.
M955 is also signed inside of Metz but M4 and M603 are not.
