The main source for the secondary and tertiary road numbers is from the PDF file at the Ministry of Public Works and Transportation: Metodologia.pdf
In those tables in pages 37-40, there were two repeated routes (235 and 716), and the newer Route 257 was missing.
As the quality of the official document is not the best, there might be missing roads that need to be added to the template. Regarding primary routes, there are 19 and that's it (As of 2019).
Besides Route 257, Route 1856 was added, which has its own unique border category.
Another source is the dynamic map based on OSM that is located in Consulta Mapa Red Vial Nacional. Roqz (talk) 16:23, 25 September 2019 (UTC)
- After parsing that dynamic map JSON sources, the following additional routes were found to be missing on 2019-09-30, and then addedd: 134, 153, 817, 937, 938, 939. Those details can be found in the members ['features'][*]['properties']['RUTA'] of the RedVialNacional_1.js resource.--Roqz (talk) 21:22, 30 September 2019 (UTC)
