Built in the commune of Hillion in the Côtes-d'Armor department, the Ponts-Neufs viaduct was built in the early 1910s by Louis Auguste Harel de La Noë. It was built for the operation of the Yffiniac-Matignon railway line and extends over 237 meters in length with a height of twenty-seven meters. The Ponts-Neufs viaduct was completely restored in 2014 and is no longer used by trains. It can be crossed on foot or by mountain bike; the site now serves as an extension of the coastal cycle path.
