Dating to the reign of emperorAugustus,[3] the bridge was on a route of the Via Aemilia, the ancient Roman road running between Ariminum (modern Rimini) and Placentia (Piacenza).[4] The bridge crossed the river Uso [it],[5] which now flows a few metres to the east.[1] In the 14th century, Galeotto I Malatesta, Lord of Rimini, replaced the bridge;[6] an arch of the medieval bridge remains extant above the Augustan stones.[6][7] The stones of the bridges, prized for their excellent quality, were quarried over subsequent centuries,[6][8] contributing also to restorations of Rimini's Ponte di Tiberio.[2][5] In October 2022, Rimini's municipal government incorporated the extant arch into a public park.[9][10]
The Augustan bridge was likely monumental, with a total length of approximately 90 metres (300 feet),[5] and numbering eight or more arches.[6] In recent centuries, Riminese historians have claimed the bridge as the place where Julius Caesarcrossed the Rubicon.[6][11]
