Stone Arch Viaduct / Bridge

[railandsail]

Here is an idea just offered,

Check out some of the products by Chooch Enterprises. I think that they might be of use to you.

I just sent them an email asking:
I wonder how thick those flexible walls are?

And I wonder how I would fashion the ring of stones that form the arch openings,.....and those proud 'columns' that stretch vertically down each footing??


There is also the possibility that these 'Chooch wall materials' could be used to make molds for casting?
