Bezons Viaduct is part of the extension to the suburban train line E (Eole) of the Regional Express Network, an hybrid transit system in Paris, France, serving the capital and its suburbs.

The viaduct connects the train line E to the existing network with a 96m-long bowstring-arch bridge that allows the lines to pass over the existing railway line on ground.

A proper concrete tensioning system was required to ensure the stability of the 2,000 tons structure: Dextra and its Tension Rods stepped in for that purpose.

The key success factor of this project, both in terms of design and customer care, was the strong collaboration between Dextra and its local partner Freyssinet.
