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).
