Construction of the Austreberthe Viaduct

The Austreberthe valley
Engineered structure

NGE was involved in the construction of a viaduct in the Austreberthe valley, creating an 18-km motorway link between Barentin and Ecalles-Alix to effectively extend the A150 and connect it with the A29. The structure comprises 5 reinforced concrete pillars and a metal structure with a reinforced concrete slab deck.
