Bridge Emilio
Located on the Tiber Island are the ruins of a bridge, known by the Romans as the Ponte Rotto, but in reality they are the remains of the Ponte Emilio (Pons Aemilius). The construction of the bridge was started in 179 BC by censors Lepidus and Marco Fulvio Nobilior and completed in 142 BC by censors Lucius Scipio and Mummius that replaced the old wooden bridge with masonry arches.
Today the bridge Emilio remains the only surviving arch of the mid-sixteenth century, when it was realized the last renovation of the bridge which had been rebuilt in the thirteenth century as a result of a flood, the Roman bridge piers remain the spur blocks travertine of the second century BC where the arch rests.
