Built in 142 BC, the Pons Aemilius, later named Ponte Rotto (broken bridge), is the oldest Roman stone bridge in Rome, Italy. Roman engineers built stone arch or stone pillar bridges over all major rivers of their Imperium, save two: the Euphrates which lay at the frontier to the rival Persian empires, and the Nile, the longest river in the world, which was 'bridged' as late as 1902 by the British Old Aswan Dam.[15] Wikimedia Commons has media related to Roman bridges. ./cache/en-wikipedia-org-2334.html ./txt/en-wikipedia-org-2334.txt
