Nahhhh, the image with all the Kato bridges was just a little Photoshop magic to give me an idea of what it could look like. Since then, due to some thinking of my own and some advice of others, I have decided to break it up a little. In the following pictures, you can see kind of where I am at now with the three bridges. The other two bridges (not in the picture) are very close but different elevations. I was thinking of trying to bash some sort of a Californian concrete arch design for both bridges (not sure how to go about this just yet). I dunno yet - work in progress!
I like the mirror idea. I've always liked the way the mirrors work but it takes some trickery to make 'em look just right... for me it does anyways. I will continue to think on this idea. Right now, towards the back, my canyon takes a sharp hook to the right and then peters out into nothing out of sight. I'm gonna have to think about where to place that mirror to make it look just right.
As you can also see, the left leg has been under development as well this week. I've pretty much gotten all the major pieces of foam cut and the rest of the terrain forming will be done with newspaper and WS plaster cloth. Currently, I am cutting pieces to act as supports for the second and third level.
Up on the third level towards the left end where I used to have the dead end branch into the mine, I have decided to be brave and attempt to add a very tight radius (8") reverse loop. I think that will improve mine operations instead of having to stop on the main and back all the way up that grade to the mine (or some kind of industry... haven't decided for sure just yet).
Thanks all for the comments. I thrive on that kind of stuff and it is really neat to get feedback.
