At its center on the roadway there is a one gate Triumphal Arch that has been restored many times. It is 13,15 m. high with a rectangular plan of 11,5 m. x 2,60 m. It is supported by the central pillar of the construction. On it there are two marble plates: on one there is an inscription with the date of construction and its devotion to Trajanus Emperor:
"To Caesar Imperator, son of divine Nerva, Nerva Traianus Germanicus Datius, Maximus Pontifex, Tribunitia Potestas for the 8th time, Imperium for the 5th time, Pater of the Patria".
