Viaduc des Coteaux-Beauclair, Railway viaduct in Noisy-le-Sec and Rosny-sous-Bois, France.
The Coteaux-Beauclair viaduct spans 580 meters across the junction of A3 and A86 highways, supporting the Paris Metro Line 11 extension.
Construction of the viaduct began in July 2019, with architect Marc Mimram designing the structure to connect Noisy-le-Sec and Rosny-sous-Bois communities.
The viaduct integrates public spaces beneath its structure, creating a promenade that connects neighborhoods previously separated by major roadways.
The structure accommodates both railway tracks and an elevated metro station, positioned 8 meters above ground level for efficient passenger access.
Metal colonnade and glass roof elements of the viaduct reference traditional Parisian elevated railway design while incorporating modern engineering solutions.
