Pons Cestius
The Pons Cestius (, meaning "Cestius' Bridge") is a Roman stone bridge in Rome, Italy, spanning the Tiber to the west of the Tiber Island. The original version of this bridge was built around the 1st century BC (some time between 62 and 27 BC), after the Pons Fabricius, sited on the other side of island. Both the "pontes" Cestius and Fabricius were long-living bridges; however, whereas the Fabricius remains wholly intact, the "Ponte Cestio
built this bridge.
In the 4th century the Pons Cestius was rebuilt by the Emperors Valentinian I, Valens and Gratian and re-dedicated in 370 as the Pons Gratiani. The bridge was rebuilt using tuff and peperino, with a facing of travertine. Some of the rebuilding material came from the demolished porticus of the nearby Theatre of Marcellus.
During the building of the walls along the river embankment in 1888–1892, the bridge had to be demolished and rebuilt, as the western channel was widened from 48 to 76
