Pont de Bornègre

The Pont de Bornègre is an ancient bridge of the Roman aqueduct to Nîmes, which also includes the famous Pont du Gard, between the communes of Saint-Maximin, and Argilliers [1]. It is located at the upper reaches of the approximately 50 km long aqueduct, 6,745 m downstream of the Eure source and 9,061 m upstream of the Pont du Gard [1]. The structure bridges an intermittent torrent, the Bordnègre, with a catchment area of 0.6–0.8 km2 and, according to modern estimates, a maximum flood flow of 5 m3/s water [1]. Its three segmental arches, with a total span of 17 m, are built of voussoirs covering the whole breadth of the bridge [1]. Two of them are buried by sediments up to the springing line of the vaults [1]. After the aqueduct fell into disrepair during the Middle Ages, the Bornègre Bridge, like its big sister across the Gard, was used as a conventional bridge for foot traffic [1].
