Road-building

The fact that in the US, where a lot of major bridges, flyovers etc. have been crumbling for basically decades after being built in the 50s and 60s, there still aren't any major old bridge collapses like this one just shows how shit these Italian ones were built.

That picture suggests the cables failed, maybe at the anchor points.
The individual bridge decks appear to be fairly intact,
suggesting the first 'armchair expert' verdict that Italian construction companies
'always have to cheat on the cement content of their concrete to pay the Mafia their cut'
isn't the case here.
