This work was one of the boldest kind of Maillarts ever made by Adriano Galli. This is the first example of arched road bridge, made of reinforced concrete and with stiffening deck in the South of Italy. This is over 170m length with two access viaducts, consisting of three-deck continuous beams on four sturdy supports and a very solid slender central arch of 80m. The disruption that caused the unavailability of the bridge had posed forcefully two essential questions: the first one purely functional and "utmost urgency," the second one of cultural and philosophical nature for the need of seismic rehabilitation increasing its functions. The urgency was to resolve at an early stage to quickly make the bridge fit for use again, at least for traffic of light vehicles. The re-functionalization, carried out in the second phase was aimed at adjusting the crossing to the new task, eliminating the mixing of pedestrian and vehicular traffic while simultaneously performing seismic retrofitting of the bridge.
Limited transit to light vehicles was ensured even during seismic retrofitting of the bridge which needed its temporary closure to traffic.
