I pass the 2 sources that I have uploaded it:

The first source is the list of the roads of the Xunta de Galicia: https://infraestruturasemobilidade.xunta.gal/c/document_library/get_file?folderId=1859420&name=DLFE-50810.pdf

The second source is the list of roads that goes along the routes, according to the typology and other details: https://infraestruturasemobilidade.xunta.gal/c/document_library/get_file?file_path=/portal-6/Documentos_DXMobilidade/Catalogo_de_Estradas_RAEGA_06_2021_.pdf

I apologize because I don't know very well translating in English.
