The roadway rested on wide piers, which were protected on both sides by arched floodways and large cutwaters.[2] The original length of the structure is estimated as 150 m, its road width as 4 m.[2] The missing spans are known to have been destroyed by flood some time before 1536.[2]The remaining arches, with a span to rise ratio of 3.3:1 (115°) or more, show a visibly flatter profile than the semi-circular arches usually preferred by Roman engineers (180°).[1][2] The rib thickness varies between one-tenth to one-twentieth of the span, corresponding to a common ratio also observed at a number of other Roman stone bridges.[3] The structure is dated to the reign of emperor Augustus (30 BC–14 AD). Immediately upstream an old water mill and its millrace is located.[2]See also[edit]List of Roman bridgesRoman architectureRoman engineeringReferences[edit]^ Jump up to: a b O’Connor 1993, p. 171^ Jump up to: a b c d e f O’Connor 1993, pp. 98–99Jump up ^ O’Connor 1993, p. 169f.Sources[edit]O’Connor, Colin (1993), Roman Bridges, Cambridge University Press, pp. 98f.
