Another idea would be to use the whole bridge as an "abandoned" railroad and turn the roadbed into a "rails-to-trails" project. You don't even have to show the whole
portion of the RxR; just a short stretch of the track and bridge with scenery depicting a cool morning and place figures as they are walking or biking across the bridge to another part of town or to a nearby park!
Since you're a modeler, you might want to check out the Lush Street Bridge in Winnebago County, Wisconsin and, while you're there, check out the Tayco Street Bridge. Be sure to look at all the photos. ;)
This looks almost exactly like the Walthers HO scale model of the Art Deco Underpass which they released a few years ago. I have purchased a couple of them for bridge modification projects. The instructions show you how to build it as a single-span, double-track bridge or to modify it by building a single, triple, or 4-track bridge. You could create a bridge like the one above by adding Rix Products wrought iron railings for the sides and remove the track on one side to show an abandoned line. My 1st will be double-track, double-span( I plan to do this by using the girder span from the second kit and supporting the 2 spans with a pier made of spackle-covered balsa or foam). Since the 2nd kit no longer contains its girder span, I plan to use a length of plywood for the ballasted bridge deck and fasten Central Valley Plate Girder sections to each side of the deck. Not sure where they will be placed as of yet, but the plans are to create interesting city street scenes for my HO scale Kansas City, Ottumwa, and Western.
