I'm afraid I do not have information about it I believe it is a route that was completed a year ago and it hasn't been updated in these resources as the latest date on them is 2023 or even 2022
The documents cited in the wiki (https://wiki.openstreetmap.org/wiki/ES:Mexico/Red_Nacional_de_Caminos#Relaciones_para_caminos) are also the latest provided by the government entity I had updated them to the latest release available.
Perhaps it will be included in the future as anny highway marked as MEX ###D is a high speed toll road so the marking as motorway is correct although I'm not sure about the MEX 175.
