Pont de Bornègre, Roman aqueduct arch bridge between Saint-Maximin and Argilliers, France

Pont de Bornègre is a Roman aqueduct bridge on the Nîmes water supply, located between Saint-Maximin and Argilliers. Its three segmental arches, with a combined span of about 17 m, are built of voussoirs covering the full width of the structure. Two arches are now buried by sediment up to the springing line of the vaults.

Built as part of the Roman aqueduct supplying Nîmes, the bridge carried the channel over the intermittent Bordnègre torrent. It lies 6,745 m downstream of the Eure source and 9,061 m upstream of the Pont du Gard. After the aqueduct fell into disrepair in the Middle Ages, the bridge was reused as a foot crossing.

The bridge spans the Bordnègre, an intermittent torrent whose catchment covers only 0.6–0.8 km² but which, by modern estimates, can carry up to 5 m³/s in flood. After the aqueduct fell into disrepair in the Middle Ages, the bridge served as an ordinary foot crossing, as did the Pont du Gard.

The site is accessible by foot along local hiking trails, though the terrain is hilly and sometimes overgrown. Wear sturdy shoes and bring water, as the paths can be shaded yet hot in warmer months.

The bridge crosses the Bordnègre, a torrent that is dry most of the year but can carry up to 5 m³/s during floods, draining a catchment of only 0.6–0.8 km². Its three arches span 17 m in total, and two are now buried by sediment up to the springing line of the vaults. The voussoirs run across the full width of the structure.
