Hi,

your edits here are of very poor quality. You are adding footways without any consideration on connectivity to the existing ways. This generates lots of error on the OSMI routing view. See https://tools.geofabrik.de/osmi/?view=routing&lon=35.27465&lat=37.04146&zoom=16&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas%2Cislands%2Cislands_car%2Cislands_bicycle%2Cislands_all%2Csnap_points%2Cunconnected_open_ends_1%2Cunconnected_open_ends_2%2Cunconnected_open_ends_3%2Cunconnected_open_ends_4%2Cunconnected_open_ends_5%2Cunconnected_open_ends_6

Why don't you tag on to the existing roads if there are sidewalks or not?
