Perrot "et al." published an article in 1971 about a Roman bridge too. The article talked about a survey in 1969 on the vestiges of the piers in the Villeneuve branch of the river the Compagnie Nationale du Rhône (CNR) destroyed them. The article also had long quotes from an unpublished report by Mr Mathian, an engineer working for the CNR. This was about a survey carried out in 1965 on the four intact piers on the Avignon side of the river. This survey found a layer of wood, at least 20 cm in thickness. This was under the foundations of each of the four intact piers.
