Some updates:
I started the other side of the bridge this evening. This side won't be seen so, while I wanted to detail it anyway, I was less precise in putting it together.
Here is side 2 with some paint
Glued to the bridge with some foam glue
I still want to do more detailing on both sides, especially with some of the pastels and weathering powders I just bought, but for now I decided to test out some scenic materials to see how it is going to look:
There is still a lot of tweaking to do, but happy with the way it is progressing. Decided to test fit some track and see how it will look when it's done!
