C, E flat and G go into a bar. The barman says "sorry, we don't serve minors". So E flat walks off, leaving C and G to share an open fifth between them.

Re: Genoa bridge collapse
I stood underneath the replacement bridge last week. Opening soon
I would post a piccy from underneath the bridge but when I click on the "Insert Image" button all that happens is this I get a "img][/img" and nothing else. Can I insert an image from my PC hard drive?

But it applies size limits (*) even if one links to a file one hosts oneself, which is crazy.

You can just post the direct link to the image with URL tags, rather than IMG tags.

Re: Genoa bridge collapse
The replacement bridge opens today! It's a completely different design; I didn't realise the new one was going to be neither suspended nor cable-stayed.

Re: Genoa bridge collapse
Wouldn’t happen here. We’d still be consulting on who we needed to consult about whether we should have a public inquiry about whether great crested water voles might be living there.
Re: Genoa bridge collapse
Not sure if the article references it but part of the design is that the number of lighting columns have been designed so that they represent each life lost in the collapse from what I recall. That's the sort of subtle but significant touch that makes this replacement project even more remarkable.Owain wrote: ↑Mon Aug 03, 2020 11:17 The replacement bridge opens today!

As for the spans, I was originally expecting some kind of cable-stayed structure to replace it given the rail yards but it looks like a conventional sequence of spans has been slotted in against them. Hopefully a dark chapter in Italian infrastructure history can be closed with this.

Re: Genoa bridge collapse
Given how quickly they have got the replacement designed, built and open I wonder if they'll look at replacing some of the other near life-expired bridges, especially as they can do the planning and potentially some of the building before removing the old?
Re: Genoa bridge collapse
There is an important difference. One of the reasons they were able to build this bridge so quickly is that it is exactly on the line of the previous bridge. For obvious reasons there was no question of needing to keep the old bridge open. In terms of statutory processes, the oversailing and planning rights were in place (or whatever the Italian equivalents were), and all the connecting roads and tunnels were complete. There was also a huge political will to get the remainder of the old bridge removed. So, admittedly on a different scale, construction of the new bridge involved the removal of the old and building a new one in the same space, which is much quicker and easier than going through the processes to build a new bridge from scratch. Compare this with the replacement of the burned span of Pont Mathilde in Rouen 7 or 8 years ago, which also took about a year.
When looking at the other near life-expired bridges they would be looking to keep the old bridge going until the new bridge could be completed, which means building the new bridge on a different alignment, with new approach roads connecting in under live traffic. A good comparison would be the Queensferry Crossing - had it been possible to strengthen or widen the existing bridge, or replace it on line while maintaining traffic flow, you can be sure that is what they would have done.
I think you'd be more likely to see significant strengthening works to extend the lives of the existing bridges, and then a more leisurely replacement of the old bridge. A major part of the justification for the off-line A14 upgrade was that the Huntingdon Viaduct which is now being demolished was life-expired. Indeed, it needed significant strengthening about 10 years ago to keep it going until the new alignment could be delivered.

Re: Genoa bridge collapse
It worked fine this morning and I checked the link... maybe it's crashed because everybody in Italy is clicking on it at the same time! There's another video with footage of the road deck, and the (existing) access roads - I'll see if I can add that when I get a bit more time.Mark Hewitt wrote: ↑Mon Aug 03, 2020 12:312 years.

Re: Genoa bridge collapse
Correction to my earlier post: the Ponte San Giorgio (it has a different official name from the original - the Viadotto Polcevera - St George being the patron saint of Genova) has been inaugurated today. I'm not sure how long before it will actually be open to traffic.Owain wrote: ↑Mon Aug 03, 2020 11:17 The replacement bridge opens today!

This is correct - I watched part of the ceremony through a live feed, and the Italian prime minister made reference to fact that the 43 lighting columns represent each of the victims of the tragedy. The whole thing was covered in Italian flags; it was quite a spectacle, featuring a fly past by the Italian air force.Bryn666 wrote: ↑Mon Aug 03, 2020 13:50Not sure if the article references it but part of the design is that the number of lighting columns have been designed so that they represent each life lost in the collapse from what I recall.

Re: Genoa bridge collapse
Certainly, one heck of an achievement to build a bridge and have it ready to open in just two years.
Hats off to our Italian neighbours.

Re: Genoa bridge collapse
Yeah. Here, we'd still be consulting people on whether or not we should have a consultation on building it.
Let's hope it's built properly though!

Re: Genoa bridge collapse
It was built in around 1 year as construction did not start until Summer 2019. It took a year for all the investigations and demolition following the collapse of the Ponte Morandi.mikehindsonevans wrote: ↑Mon Aug 03, 2020 23:13 Certainly, one heck of an achievement to build a bridge and have it ready to open in just two years.

Re: Genoa bridge collapse
Having watched the high-speed video of its construction, I assume that the engineers spent much of their childhoods playing with Lego. The various sections were made elsewhere (Germany, I think), and it looks like all they had to do on-site was put it together!
All very impressive.
