Ponte del Toro, located on the left side of the river Nera, near the municipal road, before the inhabited nucleus of the small village Toro, it is not a road bridge but a drainage channel, with its side containment walls. The artefact is therefore a hydraulic work of the Roman age to be reconnected to the drainage system of the waters from the Marmore plateau, but carried out after the reclamation works of III century BC operated by M. C. Dentato, conqueror of Sabina.

The name of the monument derives from the toponym of the place where it is located: "Toro" in toponymy means protrusion, elevation or terracing, by the Latin torus = hillin reference to the geomorphology of the place.

The recent excavation and restoration work carried out by the Sapienza University of Rome and the former Superintendence of Archeology of Umbria have clarified its chronology and function, dated between the I century BC and the I century AD.
