Development of an old railway track into a secure cycle route of 8.6 km, between the SNCF station TER of the Hôpital du Grosbois and the hamlet of Bonnevaux le Priéuré in order to open the Loue valley by an intermodal cyclo/train link. This junction will ensure continuity of route between the municipalities of the Hôpital du Grosbois and Ornans for 12.3 km. The section between Bonnevaux le Prieuré and Ornans, being already in place, is excluded from this operation. However, this development is part of the departmental cycling scheme but also in a mobility strategy at the scale of the Loue Valley and the municipality of Ornans.
