Timeline

  1. 1–100Rimini · Emilia-RomagnaUnder Augustus, stone arch bridges such as the Ponte Tiberio were built at Rimini, using precisely cut voussoirs and cutwaters on piers, becoming the standard model for imperial roads crossing rivers.
  2. 105–106Alcántara · SpainTrajan ordered the Alcántara Bridge built over the Tagus River, with a main arch span of nearly 30 meters and a length exceeding 200 meters; its inscription declares a wish for it to endure, and it remains a masterpiece of Roman stone bridges.
  3. 100–200Pont du Gard near Nîmes · ProvenceArch technology was applied to multi-tiered aqueduct channels; the Pont du Gard spans the Gardon River with three tiers of stacked arches, its upper channel precisely graded, embodying the combination of arch bridges and water supply engineering.
  4. 300–500Constantinople · ByzantineIn the late empire and early Byzantine period, arch bridges continued to be built and repaired; the floating bridge across the Golden Horn at Constantinople and stone bridges on ancient Anatolian roads carried on the Roman arch tradition, transmitting the technology to medieval Europe.
