Viaduc de Châteaulin, Railway viaduct transformed into road bridge in Châteaulin, France.
The stone viaduct stretches 165 meters across the Aulne River with eleven masonry arches incorporating kersanton and leucogranite porphyroid materials.
Built in 1906 under engineer Eugène Sanson's supervision, the viaduct connected Châteaulin-ville station to Châteaulin-junction station until 1967.
The viaduct represents early 20th-century transportation infrastructure in Brittany, demonstrating period engineering techniques through its curved design.
The structure now serves as a single-lane road bridge, providing a crossing point over the Aulne River for local traffic.
The viaduct's construction combines two distinct regional stones: kersanton for the parapet's cut stones and leucogranite for the rubble masonry.
