Autostrada: Italian turnpike; toll road; publicly built and owned, but sold off to a private company to operate during an earlier privatization pitch.

Bridge: hard to tell for sure what the section that collapsed was like, but one section still standing looks like cable-stayed. afaik, there are few if any cable-stayed road bridges in California, though a recent pedestrian bridge someplace is like that. And if you're wondering: no, it's not like the Bay Bridge; quite different engineering.

50ish years ago, the Italians were into some quite adventurous concrete construction. This bridge looks like was built during that period.

The bigger stories suggest that some maintenance was going on at the time of the collapse. I can't image what kind of maintenance might cause such a crash. I'm sure somebody will be put in jail, though; the Italians are good at that. They jailed several scientists for not predicting an earthquake.

Railroad angle: the main Italian rail line from Genoa to Rome is closed due to the collapse dumping a pile of concrete on the tracks.
