As ever, thank you for your helpful work on OpenStreetMap.

When mapping sidewalks separately, as you have done here with https://www.openstreetmap.org/way/1423550567 it helps routers if you note this on the street, in this case https://www.openstreetmap.org/way/82541916 and https://www.openstreetmap.org/way/79699823 which have "sidewalk=both" and "sidewalk=right" where "sidewalk:both=separate" and "sidewalk:right=separate" would be more descriptive.

https://wiki.openstreetmap.org/wiki/Sidewalks#Sidewalk_as_separate_way has more information about this.
