"Possibly 4th century AD" . . "13"^^ . . "6.35"^^ . "The Macestus Bridge or Bridge of Sultan\u00E7ay\u0131r was a Roman segmental arched bridge across the Macestus River (Turkish: Simav or Susurluk \u00C7ay\u0131) at Bal\u0131kesir, in the northwestern part of modern-day Turkey. Its flattened arches, slender piers and the hollow chamber system documented the progress made in late antique bridge building. A first cursory investigation of the 234 m long structure was conducted in the early 20th century, but since then its existence has been largely neglected by scholars."@en . "234.0"^^ .
