I wonder how many bridges they would have to close to traffic if they followed German bridge safety regulations and the Eurocodes.

I don't think that was the case... the bridge was there for 40 years...

This bridge type is also common in Belgium - including high-volume bridges - and they also don't look very healthy at times.

Example: E25 near Liège.

There was no repair from this time?

It was deemed as safe by the engineers who checked.

It does seem safe enough - foundations for such pillars are usually pretty deep or they sit on pilots.

Another perspective of the collapsed bridge on SS36:



You can see the high number of wheels of the truck, so it looks like a special vehicle authorized for oversize transports (it weighted 108 tons, while regular trucks weight max 40 tons).

As for ownership of the bridge, the bridge itself is under ANAS competence (like SS36), even if the road across it (SP49) is under provincial competence.

Another viaduct over SS36 has been precautionarily closed to all vehicles and pedestrians, due to a suspicious crack on the pavement.

That`s almost next to the collapsed viaduct. The Anas maybe started to check
more precisely all the viaducts on SS36.

It's also a different design of bridge, which implies that this is a general problem of poor maintenance and inspection.

Here it looks like the abutment is not strong enough to resist the lateral forces on the bridge, causing the main span to be pushed upwards. Or it could be subsidence causing the roadway to slip below the supported section.

I think they should check ALL viaducts. Some of them are really in bad condition.

Normally countries would have some bridge inspection program, usually a brief visual inspection every 2 or 3 years and a more in-depth inspection every 5-6 years. This is especially important today as many bridges are approaching the end of their design life (some prematurely).

On a happier note, Lungarno Torrigiani, the road in Florence that collapsed into the river Arno due to a ruptured water pipe, is going to reopen tomorrow (50th anniversary of Florence flooding). Italian President Mattarella is going to attend to the ceremony.

Wow, just next to the Ponte Vecchio! It's not strange that the president Mattarella wants to attend himself, I would also want to be there!

I'm surprised that our PM Matteo Renzi won't be there (or, at least, press didn't mention him), since he is from Florence and he also used to be the mayor of that city.
