This road is not Old Weetangera Road:  The latter runs through Bruce Ridge, approximately near the current bike path, then runs behind Calvary Hospital before following the route of Belconnen Way west.  See detailed route at http://www.actionheritage.com.au/uploads/1/1/7/6/117696695/old_weetangera_road_trail_notes.pdf
This road should instead be labelled Finneran's Road, all the way from Kunzea Street to Bindubi Street.
