Avignon Viaducts

Construction of two parallel railway viaducts crossing the Rhône River

Bridges

France, 1996-1998  

General description

In 1998, after 36 months of works, Bouygues Travaux Publics delivered the dual viaduct of Avignon, which allows the Rhône to be crossed by the TGV Méditerranée high-speed train line serving Avignon train station.

These two parallel structures are 1,500 metres long and rest on 40 fifty-metre high piers. 838 segments, each weighing from 110 to 145 tonnes, laid using the balanced cantilever technique, make up the 39,000 m² of the deck prefabricated on-site using the bonded joints method, which makes it possible to adjust the deck. They were designed to be able to withstand extraordinary loads: the emergency braking of a train travelling at 350 km/h or the impact on a pier of a boat sailing on the Rhône.

In order to slim down the shapes of the spans, the viaducts are made up of geometrically variable segments whose height gradually decreases from the support towards the middle of the span. Designed with posterity in mind, the Avignon viaducts blend perfectly into the landscape thanks to their white cement concrete, reminiscent of the limestone of the Angles massif and the immaculate colour of the walls of the Palace of the Popes.
