Here's what I did and all for less than $20!

yes, I will try to post the photos full size, I have them on e-files and everything, but I am having a lot of trouble posting them with the new forum format.  It seems that linking the URL simply doesn't work like it used to.  What I need is an 8 year old kid to show me

Jack - the photos of your viaduct in the other thread that you linked to are so small I cannot see them clearly. Do you have them posted anywhere in original size?

I made my viaduct by verticaly sinking some pvc pipe into the ground as pylons, fabricating a road bed with 3/4 pressure treated plywood screwed to the top of the pvc, then the viaduct itself I made from pink insulating foam board covered it with chicken wire and finished it off with a layer of stucco to look like concrete.

I dont' see why you couldn't use a similar method with some quick release pins to hold the viaduct in place.  The foam weighs nothing and depending on how you wish to finish it the all up weight is very minimal.

Well I would make it out of wood and then render the outer sides of it to look like stone using something like carved Polystyrene foam.

I am considering using a removable "stone" viaduct to extend the track from a raised garden bed out over a patio to allow larger radius curves on a model UK railway. I want to be able to lift up and remove this viaduct accasionally, so i need a way to fabricate a curved British style stone  viaduct that is reasonably light in weight.  Any ideas?
