Monumental work that allowed the Via Flaminia crossing the Black River, built in all probability during the seventh consulate of Augustus (27 BC) when, for military reasons, it became urgent restoration of the old street. The daring building, located between the slopes of Monte Maggiore, on which rises Narni, was praised already by ancient authors and depicted by artists and travelers and is one of the most significant creations of Roman architecture and engineering. Of bridge will retain in full the two arches of the head and the remains of two stacks of the central arches, while the collapse of the third pylon is still visible in the river bed. The work was built on the western branch of the Via Flaminia, considered the oldest, which branched off at the altitude of Narni and headed for Carsulae and Bevagna. On this route you can take a trip to the discovery of other bridges, all restored by the emperor Augustus, who testify to the role played by the Via Flaminia in Narni.
