a bit labyrinthine but still the best route through the suburbs in this direction, combination of separate bike paths and quiet streets (and just one intersection with traffic lights), path continues to Hyrylä and beyond in the north
now mostly with new destination signage, with some gaps of course (plus the official route to the centre goes via Yhdyskunnantie instead I think), older signs at the southern end of this route point to “Helsingin pitäjän kk” when heading north
