Phase 1 of the project carried out by the Doubs Department aims to create a major work of art on the commune of Colombier Fontaine, part of the site of a section of EuroVelo 6 (EV6), between the municipalities of Dampierre-sur-le Doubs and Colombier Fontaine. This section is a break with the level of service and security observed on the rest of the EV6 route. The work consists of the construction of an estacade, along the RD 126 on the banks of the Doubs, whose original structure by its design allows a good landscape integration.
