Hi mdelatorre, thanks for mapping! I noticed here (changeset/109486687) that you changed the ref tag on Libramiento Ruta de la Independencia Bicentenario from EM A7D to MEX A7D. My research indicates that the MEX prefix is reserved for federal highway routes, whereas the abbreviation EM is used to differentiate state highways in Mexico State (see osm.wiki/ES:Directrices_de_etiquetado_mexicanas and osm.wiki/ES:México/Etiquetado_de_v%C3%ADas). Based on these pages, state routes can be identified by their unique highway shield. This signage indicates that both A6 and A7 are state routes and probably should be tagged as EM A6D and EM A7D: (https://www.mapillary.com/app/lat=19.389780062791&lng=-99.708504111047&z=17&pKey=485605485842159&focus=photo). Thanks, and let me know if you have any questions!

Hola joshieadalid, ¡gracias por el mapeo! Noté que cambió la etiqueta de referencia en Circuito Exterior Mexiquense Bicentenario de MEX 57D a EM 5D de (way/843985245) a (way/27393480). La señalización en el área indica que la autopista aún puede ser MEX 57D (https://www.mapillary.com/app/?lat=19.613836288451992&lng=-99.04013061523403&z=18.292580594350053&pKey=473526597210773&focus=photo). Tengo curiosidad, ¿qué fuente usaste para estos cambios? ¡Gracias!
