I think it's a bit silly to compare the durability of something the the Parthenon to a modern structure - bridges and highways in particular. If the Parthenon carried daily freeway traffic for many years, it likely would not be standing.
Describing the Parthenon as being in "excellent condition" is equally silly.
Yes, it's in pretty decent shape for being 1900 years old, but describing it as "excellent condition" is ludicrous. That's a structure I would describe as "crumbling".
Let's also not forget that many-storied buildings are subject to stresses not found in ancient Greek and Roman construction.
Rusting rebar probably has something to do with it, but they're really comparing apples to oranges here.
