10. Conclusions To save and at the same time preserve the historical value of the fire damaged Ponte di Ferro, an iconic and crucial link between the Ostiense and Portuense banks of the Tiber River that required, also, an important enhancement, a new “post-industrial” style bridge has been erected.
