FRA: Massive downgrade of autoroutes & routes nationale

[michih]

• Auvergne-Rhône-Alpes (ARA):
  • N102

The segment through Le-Puy-en-Valey was downgraded to D902 in 2021. D906 was upgraded to N102. See 2024 GSV. N102 should have been transferred to the region from 2024-01-01 but is announced to be transferred on 2025-01-01 now.

Nonetheless, a new N102 section was opened today I've added it as "N102 Arvant" albeit I assume that it should be plain N102, and the old route (only RMA58 and me have traveled it) should be N2102 now. It is all announced to be downgraded to D routes in just two months.
