The Bezons Viaduct is part of the extension of Paris’ suburban train line E (Eole), a hybrid transit system connecting the capital to its suburbs. This viaduct features a 96-meter-long bowstring-arch bridge that links the new train line to the existing network, allowing it to pass over an active railway line below.

To ensure the stability of the 2,000-ton structure, a robust concrete tensioning system was required, and Dextra provided its Tiges de tension for the task.

Dextra Tension Rod System is a high-performance solution designed to provide structural stability in various construction applications, particularly in bridges and viaducts. It provides a reliable method for applying and maintaining tension across structural elements.

The success of the project, both in design and customer satisfaction, was driven by the strong collaboration between Dextra and its local partner, Freyssinet.
