Railway viaduct of La Garde-Adhémar
The viaduct spans the canal of Donzère, parallel to the Rhône river, underneath the village of La Garde-Adhémar near the motorway A7.
With its 324-meter-long deck, it is one of the major bridges on the high speed railway track Lyon-Méditerranée.
It has four spans : two 52-meter-long side spans and two 110,30-meter-long main bowstrings.
A central arch linking both arches increases slightly the rigidity.
The steel arches support a concrete deck.
