Most of the cycle route is signposted, although, at time of writing, there were sections where the signposts still had to be put in place:
- Signposting to be put in place in the north of the county of Seine-et-Marne
- Signposting to be put in place between Ablon-sur-Seine Lock and Juvisy-sur-Orge bridge, and between Corbeil-Essonnes (in the county of Essonne) and Melun (in the county of Seine-et-Marne)
- Signposting to be put in place between Briare and Séligny (at the junction with the Vienne): follow the Loire à Vélo cycle route for a time, then the EuroVelo 3-Saint-Jacques à Vélo via Tours
- In the county of Gironde: signposting has not been put in place along the sections simply providing provisional continuity along the route.
