The connections between the Northern quay of the DuriaMaior, where the Eporedia was, and the Southern one was guaranteed by the Ponte Vecchio, which even today preserves the Roman structure at the base with only two asymmetric arches, and the even more monumental Ponte Maggiore, build approximately 500 metres downstream. The remains of the structure, emerging the first time in the river bed during the flood of 1977, they were studied and documented during the work restoring the banks after the exceptional flood of 1993.
The bridge, approximately 150 metres long, was presumably built in the I Century AD and collapsed after a violent flood that occurred in an unspecified era, maybe not much after it was built.
The ten arcades of the bridge, with the four central ones larger than the side ones, were each made of five parallel stone arches, filled with a conglomerate cast and resting on eleven concrete piles with an ornamental facing of stone ashlars, based on the alignment of wood poles with metal tips, deeply fixed into the sandy riverbed. The bridge supported a paved road, with a carriageway 5 and a half metres wide, flanked by tight pavements (0.45 m) and protected by parapets exquisitely shaped like a bull.
In correspondence of the bridge, the bank along the Lungo Dora was contained and protected by a quay more than 100 metres long, at its western end there was a sewer line from the town, probably also used as a towing route for boats up to the docking.
