Pont Serme

The Pont Serme or Pons Selinus, later called the Pons Septimus, was a Roman bridge of the Via Domitia in the Aude department, commune of Coursan [1]. The approximately 1500 m long viaduct crossed the wide marshes of the Aude River and the Etang de Capestang west of Béziers, surpassing in length even the Trajan's Bridge over the Danube [1].
