Hi thank you for your observations. The road "Castaño" https://www.openstreetmap.org/way/680187815 to https://www.openstreetmap.org/way/680187814
is indeed reversed, I must've missed that.
As is the segment of Avenida Chac Mool's (https://www.openstreetmap.org/way/679585831), It was my mistake

I do not have access to the roads
Privada Paraguay (https://www.openstreetmap.org/way/167490598),Privada Uruguay (https://www.openstreetmap.org/way/167490614), and Privada Argentina (https://www.openstreetmap.org/way/167490605)
as they're in a gated community I do not enter, but by different satélite images it does seem they're one way, the cars parked alongside them seem to go in one direction only.

I missed the connectors in my recent update, the classification of the roads alongside are correct I'll take my time setting them up, I'd appreciate your help if you see any of them.
As well as correcting the direction of the way in my recent updates.

I must've missed the email regarding the Mérida updates. The México OSM Wiki says 3 different things and are contradictory (regarding the classification of Federal "carreteras")
In one of them it mentions that this "ways" are "principal or trunks"


It would be great to settle this out as it isn't clear 

I have reclassified the ones within the city and within other towns to primary.
