There is no road on this viaduct, just a railway! Komoot won't suggest it to you anyway. The road passing at the foot is a fairly large country road but pleasant. When it is not cluttered with brambles, it is possible to take a pedestrian and cycle path bordering the road on the pond side when leaving Le Relecq Kerhuon, up to the first crossroads (direction Le Douvez, Landerneau).

This is not the case everywhere, but here a lot of effort has been put into putting markings on the road to "protect" cyclists - even in town.
