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.

Majestic arched viaduct, it is part of the many works of art in the Bay of Saint-Brieuc built by engineer Harel de la Noë at the beginning of the 20th century. 10 m high and 58 m long, it spans a small stream, which once allowed the Chemins de fer des Côtes-du-Nord line to connect Saint-Brieuc to Moncontour.

A path rather than a road that comes across a somewhat unexpected passage with a beautiful view from above.

The Greenway - and the Percée Viaduct - a fascinating story, which can be read on the information panels and is very interesting to me. Here's a translation of Vaduz: Like elegant young ladies striding over the valleys of the Lilliputian kingdom, at the beginning of the 20th century, nine viaducts, including the Parfond de Gouët Viaduct, with their beautiful brick arches, stretched along the very first railway line of the local network, St. Brieuc - Plouha. These engineering structures, built by a native of the region, Louis Harel de La Noë (1852-1931), a bridge and road engineer, allowed the small train of the Côtes-du-Nord to follow the winding and steep coastline without much effort. Lightness and elegance are the words that come to mind when describing the architecture of this 1903 building, characterized by numerous columns and arched vaults and its masonry in warm brick colors. The techniques used demonstrate boldness, ingenuity, and originality: reinforced concrete anchors (rebars) were installed to increase the compressive strength of the pillars and prevent cracks.
