Pont Antoinette, Railway arch bridge in Sémalens, France.
The Pont Antoinette extends 89.30 meters across the Agout river, featuring stone construction with a single arch that carries both rail and road traffic.
Engineer Paul Séjourné designed and completed this dual-purpose transportation structure in 1884 during the expansion of French railway infrastructure.
The bridge represents a period of industrial advancement in French engineering, combining railway requirements with local architectural methods of the 19th century.
Regular maintenance inspections ensure the bridge remains operational for train passages while accommodating vehicle traffic on its upper level.
The structure demonstrates how a single bridge can efficiently serve two transportation purposes through its innovative dual-level design.
