The Pont Ambroix or Pont d'Ambrussum (French for Ambrussum Bridge) was a 1st-century BC Roman bridge in the south of France which was part of the Via Domitia. It crossed the Vidourle at Ambrussum, between today's Gallargues-le-Montueux in the Gard department and Villetelle in the Hérault department.
Ambrussum contains three archaeological sites of international importance: the Colline de Devès which was first occupied in 2300 BCE and settled as an oppidum between 300 BCE and 100 AD; the Roman staging post on the Via Domitia which had hotels, a baths and industrial buildings; and the Pont Ambroix.
The bridge was sketched by Anne Rulman in 1620 and the drawing shows only four arches. A 1839 lithograph and a painting by Gustave Courbet (1857) show two arches.
The Vidourlades are violent floods or crues on the Vidourle, During a crue, the water flow increases from a minimum of 3 m3/s to over 3000 m3/s. Floods were recorded 8 October 1723. The floods of 18 November 1745 reduced the bridge from four arches to three. Further major floods occurred 6 October 1812, 21 October 1891, 21 September 1907. The floods of 7 September 1933 reduced the bridge from two arches to the one we see today.The site was abandoned when transit patterns changed; the Domitia became less important and the community relocated to Lunel-Viel which better served a north–south transit pattern, but the bridge continued in use till the late Middle Ages.
The bridge is a Mérimée list National Monument No. PA00103057. The oppidum is a Mérimée list National Monument No. PA00103760
