La Roche-Bernard bridge, Suspension bridge abutment in La Roche-Bernard, France
The La Roche-Bernard bridge is an iron suspension bridge built in 1839 that spans approximately 198 meters across the Vilaine River. It rises about 15 meters (50 feet) above the water and connects the towns of Marzan and Nivillac.
Architect Pierre Leblanc designed the bridge in 1839 using iron wire cables as a new technology for the time. After wind damage occurred between the 1850s and 1870s, authorities eventually added a modern replacement structure in 2004.
The bridge connects two communities and was once a sign of progress in the area. It made crossing the Vilaine River straightforward without long detours.
Access is on foot only, as pedestrians alone are permitted and vehicles cannot cross the historical structure. The best time to visit is in calm weather, as the bridge is quite exposed to wind.
The original bridge supports still stand alongside the modern 2004 structure, showing the old construction method. Visitors can see both building techniques side by side and compare how engineering has changed over time.
