I wonder if it was a spontaneous collapse, there don't seem to be any vehicle on it.

The two policemen were parked below the bridge to perform controls, when they heard strange noises and ran away by foot before the bridge collapsed over them. Pure luck.
That's the 3rd bridge collapse in the last 6 months in Italy, that's very sad. I think in Italy we have a generalized problem of scarce maintenance and early problem detection on our infrastructure.

The articles says 'causes are still unknown'.

Historical imagery in Google Earth suggests SS 231 around Fossano was built in the early 1990s, probably opened in 1993 or 1994.

Wikipedia says 2000.

The expressway section has stub ramps on each ends, I once heard it was built in anticipation of the A33 which once done it would have used it as a part of its alignment (and apparently, the plans changed since A-33 follows a different route).

It could be, the historical imagery in Google Earth has extremely low resolution, you can only see the difference between earthworks and paved. It shows earthworks in that area as early as 1989.

Apparently it would have been to be completed in 1994, costing 40 billion lire (20 million euro) but the company went bankrupt and it was completed by a different one.

I guess because what has failed was an exit ramp, and not the deck of the main carriageway.
Here the right location of the event.

Yes, the offramp to a nearby exit collapsed. If the bridge was built in the 1990s, it is not very old, hence it would not require very extensive inspection yet.

It seems like it is an in-situ poured girder, it's a massive structure. They are very heavy compared to pre-fabricated beams or girders. Perhaps a miscalculation during design? Normally a structure this young would not spontaneously collapse, even without maintenance.

If You look with GSW the girder seems to have 2 joints, as it was build with 3 massive parts put together in-situ with stressed cables. Bad assembly? Bad sealing of the junctions->corrosion of the cables?
The 1/3 of the girder collapsed on the carabinieri's car seems completely disconnected from the second third. The second third has a secondary crack occurred while hitting the ground.

Thankfully, nobody was seriously injured or killed in this accident.

This being said, it is interesting to note how people generally fret when told that most bridges are not, by design, welded into their pillars, just supported.

The conditions of another bridge, in a small town in province Brescia, are of serious concern. In a picture the incredible solution used to secure it:

Wow, that's really crap. This bridge carries SS42, an important link between northern Lombardy and Trentino with a lot of (also heavy) traffic.

SS42 should become a tolled expressway, and they should improve it north of Berzo Demo (from where it is an old road, not an expressway), all the way to Ponte di Legno (at least).

One urban overpass in Turin, Corso Grosseto, has been closed to trucks and its max speed reduced to 30 km/h for everyone else. In March some pieces of concrete fell from it and it is constantly monitored since then, in the wave of recent collapses of other bridges.



This overpass is destined to be torn down in the near future, following the dig of a railway tunnel underneath and the complete redesign of the surface roads and intersections.
