Jules Verne Viaduct

About

The Jules-Verne viaduct is a road bridge crossing the Somme, the Hortillonnages and the Paris - Lille line, east of Amiens, on the territory of the municipalities of Camon and Glisy, in order to allow the eastern bypass of the Amienese agglomeration (national road 25). It bears the name of the French writer Jules Verne.

Presentation: Designed by architect Charles Lavigne in prestressed concrete and 943 m long, it was built in two phases: it was commissioned in 1987, it was doubled in 2002 and is now 2 × 2 lanes. In its first phase, the viaduct was built by Campenon-Bernard. The viaduct was doubled by the second viaduct by the company demathieu & bard.

Characteristics: Since the aprons of these structures are straight in elevation and plan, they were made by the method of construction by push for the first time in France. This method consists of making the apron by concrete sections at the back of a abutment on a prefabrication area and moved by push over the breach to be crossed when the concrete has hardened enough to prestress it, before making the next section.
