Thanks. Fixed already.

Hello Luke,

Together with user Josuer we are working to fix the mess with respect to Mexican highways. Unfortunately not every road has a road number and really often the road signs are mistaken due to a lack of standardization of state authorities that don't follow the standards in place by the federal government.
In the following weeks I will be fixing nomenclature of highways in the State of México. I have found route numbers that do not even exist. Our source will be SCT, INEGI and IMT. We have made a wikipage where all the information regarding tagging highways in México and a wikipage for each state's highway. This process will take time. In regards to highways 6-AD and 7-AD I am now sure they have state jurisdiction but unfortenely road signs are mistaken with the wrong shape and name tag.

Miguel no tengo idea a que te refieres. Esta carretera la mapea recién fue estrenada. No veo que exista un error de dirección. Son dos carriles en un sentido y dos en el otro.
