Hi ilias ,
Thank you for connecting with me.
I already know that a road with a ref that starts with RR is better classified as a secondary or primary road.
But in this case, I just unified the classification on the same street. because there are classified parts "tertiary" by the user "Cyrille37"
EX:
https://www.openstreetmap.org/way/88278918
https://www.openstreetmap.org/way/257579951
https://www.openstreetmap.org/way/361349985
And other parts classified as secondary  by the user "Cyrille37"
EX:
https://www.openstreetmap.org/way/415318562
https://www.openstreetmap.org/way/89618582
https://www.openstreetmap.org/way/134641547
The reason for modifying the classification is that some streets are better left as tertiary to align with the nature of the region.
