The Pont Flavien (English: Flavian Bridge) is a Roman bridge across the River Touloubre in Saint-Chamas, Bouches-du-Rhône department, southern France. The single-arch crossing, which was built from limestone, was on a Roman road - the Via Julia Augusta - between Placentia, Italy and Arles. It is the only surviving example of a Roman bridge bounded by triumphal arches from the Augustan period, although similar bridges probably existed elsewhere, as indicated by portrayals on coins of the late 1st century BC.
