Yes, seriously. As I understand the situation there were no 'facilities' at all on the Severn Bridge itself, and as the bridge took shape it was a long and precarious walk in sometimes foul weather conditions to land.

Many of those working in construction are paid on piecework as it were, so why would you spend an hour walking to land?

Ureic acid and other bodily products are known to be corrosive to most commonly used metals including stainless steel, especially if contamination occurs before anticorrosive primers are applied.

Similar problems affect street lighting columns owing to canines leaving their calling cards, but on a much smaller scale.

I don't know much about the Morandi Bridge in Italy but it appears to be more of a modular reinforced concrete construction. As I understand it the theory at present is that steel reinforcement had corroded inside the concrete, and the consequent expansion of rust had fractured the concrete, weakening it. In such structures steel provides tensile strength whilst concrete provides strength in compression. However, the design is such that most of the strength is compressive, and that would have been compromised by fractures.

The bridge is in an elevated position close to the sea so it is highly exposed. There was also a large steelworks in Genoa until very recently on the seaward side which would have provided a corrosive atmosphere. I am counting my blessings on that score because I have crossed that bridge more times than I care to remember, in all sorts of weather throughout the year. (The Morandi Bridge is located on the main coastal route between Genoa and Genoa Cristoforo Colombo Airport.)

Father in law worked on the first Severn Bridge. I found a couple of old photos of some precarious looking construction work.

Concrete fence posts go the same way. A couple of ours shed the concrete over about a 250mm section, exposing the rusted steel reinforcing. Once moisture penetrates the concrete, failure is inevitable.

Indeed. The usual 'repair' method is to cut out the cracked concrete and to replace it; often cladding the structure with an additional layer of reinforced concrete. We often see motorway bridge supports repaired in this way.

This may work well where the load is almost entirely compressive, (as in motorway bridge supports), but any bending moment will weaken an already weakened structure.

The problem with much of the Morandi Bridge was that it was at a high elevation and overhead, which would have made any such repairs very difficult. I believe it was also principally of concrete construction, whereas similar structures in the UK tend to use more steel.

Don’t forget all the bodies of Mafia victims added to the mix, that can’t help the strength of concrete!

You have just become a grass!

Can you swim (with the fishes)?

It might explain the extremely messy remnant of Dobbin I guess!

Well this is true. The Mafia are said to be heavily involved in the Italian concrete industry!

Equally there are concerns about the Chiswick Flyover in London, where fractures have also been found. X-Ray imaging suggests that there are human body sized cavities in some of the supports, which were cast when the Kray Twins still ruled much of East London.

But Chiswicks in West London so it couldn’t possibly have been them!

Re: Newspapers read

When I was a lot younger and got out more, I have to confess I read many, many different newspapers.

These day's, I tend to come on here to catch-up with all the latest 'real' news and not the fake stuff. that is so proific.

I do miss reading the various newspapers... almost as much as I miss a fish & chip supper on the way home from the pub.

When I travelled around the UK more I often stopped at a Little Chef and took advantage of a 'free' newspaper there. I could become totally engrossed in a newspaper; any newspaper really for an hour or so until I needed to get moving.

Maybe newspapers were different then?

I still do it on the train if there is a free paper, but rarely seem to get time at home.

" A reader noted that our recipe called “Spaghetti with radicchio, fennel and rosemary” didn’t include spaghetti, fennel or rosemary. The ingredients and method were right, but it should have been titled: Strozzapreti with radicchio and balsamic (1 December, page 9, Feast)."

Yeah - a real 'howler'. Fortunately they get the important things right, like Brexit!
