Hello muralito,

Thanks for reaching out. I did base these directionality modifications on evidence gathered from Esri World Imagery. I saw that https://www.openstreetmap.org/way/584764547 has a car positioned in the direction of travel, which suggest its intended for oneway traffic. This way and https://www.openstreetmap.org/way/584764546  are both narrow and appear to only have one lane each.

After some careful re-examination of the location with available ground imagery, Mapillary Imagery from December 2024 (https://www.mapillary.com/app/?lat=-34.7940868&lng=-56.117815&z=17&pKey=1574085230144163&focus=photo) appears to suggest this directionality with the stop sign facing that lane and entrance to Camino al Paso del Andaluz. https://www.openstreetmap.org/way/164248325 looks to be only wide enough for one car and the Mapillary driver’s direction is heading east on it. There is another sign facing the driver’s perspective (https://www.mapillary.com/app/?lat=-34.793422199999995&lng=-56.116333499999996&z=17&pKey=1106031997568400&focus=photo), although it is not conclusive that it is only a oneway road in that direction but it seems that way by the width and all indications. 

Apologies for not including the Mapillary citation in the original changeset. If you have insight that these resources are outdated and directionality has changed in 2025, I am happy to defer to your knowledge. Thanks!
