On a rare visit to the Toute de France thread, I chanced to see a photo of a fine arch bridge by the name of Pont Napoleon, with a question as to how it was built.
Wikipedia was strangely silent on that topic, but a quick Binge found:
which not only had a description of how the bridge was built, but something I wasn’t expecting:
Which must have been taken in 1860.
Roughbarked posted an image in the TdF thread, but for some reason it doesn’t display for me.

Try copying it to the desktop & opening it from there. Seems to work well for me.
What did you copy to the desktop?
If I click on “quote” I can copy the link, but it just takes me to Startpage if I paste it in Edge.

Right click, copy image.
How can you copy image when there is no image?

Copy link then. (It only works sometimes & I have no idea why)
There is nothing displayed in the post to copy.
I can copy the link if I open the post by clicking “quote”, but the link doesn’t take me to an image, it goes to the Startpage search site.

Then I have reached the limit of my knowledge. Sorry.
No problem :) I was hoping roughbarked might have another go at posting it.
In the mean time, here is
a history of photography
You’ll have to search via startpage for Pont Napoleon the go through all the Image results to find the matching url.

No, they displayed no problem.
The roughbarked one was showing the bridge during construction (I presume), so it may have been the same as the one I posted, but might also be something different.
So where’s roughbarked when you need him?

Thanks for asking the question :)
Given the prominence of the bridge, the unusual construction method, and the age of the photograph, I’m surprised it didn’t make it onto Wikipedia.
Maybe it’s a copyright thing.

I am surprised by the 1860 date, I was thinking it was much older at first glance. I only got a few seconds to look at it as the riders went over,

Sure does.
the correct forum response is to say “no worries” and take the credit for someone else’s work :)

No wukka’s mate. ;)
Nice photo.
Yes, this was pretty much the standard way to build arch bridges at the time.
Wooden scaffolding is first built up in one or more towers from the valley floor, then branching out at the top like a tree to join the tower(s) and backs together. Then builld a timber arch on top of the branches. Then use the timber arch to build the brick arch on. Then the deck.
The timber is going to rot away anyway or be swept away by floods, so remove it slowly to transfer the load onto the brick arch.
Similar for buildings with arches and domes.
