The Pont Serme or Pons Selinus, later called the Pons Septimus, was a Roman bridge of the Via Domitia in Hérault, southern France. The approximately 1500 m long viaduct crossed the wide marshes of the Orb River and the Etang de Capestang west of Béziers, surpassing in terms of length even the Trajan's Bridge over the Danube. Today, very little traces are left at the site, save the name proper which passed over to a village nearby.
