Bicycle route https://www.openstreetmap.org/relation/1102531 pass here but pedestrian way are now marked without bicycle=yes 

Not passed by there today to check if there is some change here but it's mostly improbable. (pin + Avenue des trembles northbound + connection to Centenaire.
West part of tagette is more borderline as there is a C3 without exception comming from Gros Tilleul, but no indication going to Gros Tilleul.
