Neal, nice post. Interesting way to do the dowels. Hope they line up OK.
That bridge is MTH? Pretty awesome, pretty big! I used two old Lionel girder bridges on my table layout, for the upper level. Too high for those plastic pylons, so I used a 3 inch basswood plank underneath them for support. Works fine, no sagging at all. I'd be really interested to see that baby up there, and how you mount it. Also, those boards and brackets.
