Located in the commune of Hillion, in the department of Côtes-d'Armor, the viaduct of Ponts-Neufs was built in the early 1910s by Louis Auguste Harel de La Noë. Installed for the operation of the Yffiniac-Matignon railway line, it stretches 237 meters long and twenty-seven meters high.
The Ponts-Neufs viaduct was fully restored in 2014 and no longer serves the passage of the train. It can be covered on foot or by mountain bike, the site now serving as a continuation of the coastal greenway.
