In general Italy builds transit infrastructure cheaply by European standards (which means massively cheaper than North American standards). Despite real concerns about corruption or ineffective bureaucracy they've managed to improve their rail infrastructure a lot these past few decades. Germany and the UK look very bad compared to them in this respect
Given that bridge was in its 5th decade, I don't see how that applies to what the Italians have done in the last couple of decades, unless you're arguing what they are building today will be tomorrows Morandi Bridges?
i have no idea what the italians have been doing. i would observe that in the uk most bridge failures were in the 19th century, when the properties of materials such as cast iron were not too well understood - same lack of understanding that the morandi bridge seems to have had much more recently.
