France(1st–5th c. AD) The Pont Serme (also Pons Selinus or Pons Septimus) was a Roman bridge spanning 1,500 metres along the Via Domitia in what is now southern France[1]. This massive viaduct crossed the marshlands of the Aude River and Étang de Capestang west of Béziers[1]. At 1.5 km in length, it surpassed even Trajan's Bridge over the Danube, making it one of the longest Roman bridges ever constructed[1]. Only fragmentary remains survive, though its name endures in the nearby Domaine de Pontserme vineyard[1].
