Still, not bad for 1950 years of age, and missing 2/3rds of its original materials. I doubt any current stadium will have such an existence. The Flavian dynasty consisted of just three emperors, and lasted about 27 years. They really got things done back then.
Can't find my picture which shows both, but below the modern bridge over the Guadalquivir in Cordoba Spain (apologies if I googled the wrong one but then there's a similar one there) and the Roman bridge. Makes you point.
