The Bridge of Gemarrin is a Roman bridge in the vicinity of the ancient city of Bostra (modern-day Bosra) in southern Syria. The bridge belonged to the Roman road to Soada Dionysias (As-Suwayda), crossing the Wadi Zeidi some kilometers north of Bostra.Today, the structure presents itself essentially as an arch skeleton: while the three semi-circular arches, made from local basalt, are still extant, the roadway and the fill have been removed to expose the top of the arch vaults.
