The Ponte d’Augusto (Italian for "Bridge of Augustus") is a Roman arch bridge in the Italian city Narni in Umbria, built to carry the Flaminian Way over the river Nera. Of the original four spans of the 160 metre long bridge, only the southernmost remains standing.
The bridge was built under Augustus around 27 BC using marble blocks. The 30 m high structure was one of the largest bridges constructed by the Romans.
According to the Umbrian Superintendence of Archaeological Heritage:
- The complexity of the structure and a number of irregularities suggest that its construction was a lengthy affair. Evident signs of ancient restorations reveal structural failures resulting from intense use or from natural calamities. Chronicles from the Middle Ages report collapses caused by floods and earthquakes. Documentation gives a definite date for the collapsing of the third pylon, which occurred in 1855. During the 1970s reinforcement work was done on the bridge. The surviving arch has suffered damage from recent earthquakes, in particular the 2000 quake. Restoration work is now in progress.
The bridge was a popular destination on the Grand Tour.
- There are few relics of antiquity that impress the traveller with greater ideas of Roman magificence that the sight of this bridge affords... It is built with large blocks of white marble, neatly squared and fitted in, but without any appearance of cement having been used, or even cramps of iron to connect them together.
Hakewill states that a description of the bridge is to be found in Roma antiqua et restaurata by Biondo, of Forli, 1558 [sic]; and he also quotes from antiquity an epigram of Martial in which the bridge is mentioned.
Probable width of the four original spans: 19.20m, 32.10m, 18.00m and 16.00m, of which the first, southernmost arch remains standing.
- The reference is presumably to De Roma instaurata (Rome Restored, 3 vols, 1444-1448) by Flavio Biondo
- Martial, Epigr. vii. 93, 8
