This is an OpenSCAD file to create customizable Unitrack bridges. It's similar to the Kato Viaduct bridges, but with a flat bottom. Kato has a limited selection of sizes, so this lets you create whatever size you need.
You can select from 4 common unitrack radii, pick a length in degrees, a height, and a deck width. I have not had much luck with the customizer on Thingiverse, so if you want to customize, it's probably easier to just load the .scad file in OpenSCAD to generate your own customized STLs.
I have uploaded a couple STLs of various sizes as examples.
The code to do arcs in this is from JustinSDK:
