Today, the structure is surrounded by thick vegetation, and serves only to carry a wood shed. The bridge has a span of 6 m, a width of 3.3 m and is built of travertine. The walls of one ramp feature two flood arches, one of which has a segmental shape and runs from the ground to the quarter point of the main arch rib. A similar segmental relieving arch can be found at another Roman bridge in central Italy, the Ponte di Pioraco.
