Hello Hannah,

here is one example: Your duplicated new way is this one: https://www.openstreetmap.org/way/1278694757 , but this road is already mapped here https://www.openstreetmap.org/way/671789980#map=17/-37.82372/144.67432 . There are three problems with this approach: the road is duplicated, the cycleway tags are redundant as this cycleway is already explicitly mapped here: https://www.openstreetmap.org/way/970925776#map=18/-37.82130/144.67459 and last the duplicated way is unconnected to the rest.  Therefore errors are displayed on the OSM inspector routing view page, see https://tools.geofabrik.de/osmi/?view=routing&lon=144.76128&lat=-37.73940&zoom=10&baselayer=Geofabrik%20Standard&overlays=unconnected_open_ends_1

thanks
