The Flaminia, in Cantiano, crosses the swirling Burano torrent by a bridge characterized by two powerful arches, which led to the current name. Only the upstream side has many chipped and refurbished manufacts, especially in the central watershed, which had to withstand winter floods for two millennia. The massive central stack is 5.40 m large on the upstream side and 7,45 m on the downstream; it follows the current in the most favorable manner and determines two divergent arches at the sides, made to accommodate the flow of current as better as possible not to counteract the water pressure. They are about 7 m wide and rest on a low, slightly protruding, row of bricks on the upper edge of the central stack.

It is the best preserved bridge along the consular road on the Adriatic coast, together with that of Augustus in Rimini still in use for local traffic. It is built in cornelian stone dug in quarries still existing in the gorge, with materials set up in a not homogeneous way; both the ferrules of the two arches, and part of the soffit masonry are built with large blocks, squared with extreme regularity.

In the remaining structures, however, the facing consists in rows of different thickness slabs without mortar, in a kind of rough ashlar. The whole processing results very careful in the main structure and less for the remaining parts.

Maintenance and restoration interventions are present in archive documents, since the sixteenth century.
