il Ponte di Tiberio, was started during the reign of Augustus, as part of his extensive series of public works for Rimini, but takes its name from Tiberius, the Emporor under whose reign the bridge was finished. Built in seven years, between 14 and 21.AD. http://www.visit-rimini.com/general-sightseeing/il-ponte-di-tiberio-the-tiberius-bridge/
