Ron:
Thanks very much for these thoughts. I was going to head in the direction you describe, but it's somehow quite helpful to see it all written down by someone else.
Yes, this particular rise won't cause one track to rise over another. We only need to have enough of rise/fall to simulate the subtle arch of a suspension bridge. Something like:
The plan is that, if we find the grade to be too steep for the available length, we will do a "fake out" effect of making the side girders more steeply arched than the actual roadbed.
This bridge is 1-2 miles from our home, btw. The span that you see in the photo will be about 8 feet on the layout.
