New back ground building and bridge construction

I purchased a Walthers back ground building and as usual I threw out the instructions and started making it fit. I have actually just about finished it but have not photographed the area. The overpass concrete guard rails have been assembled and set in place temporarily here. I have since added the deck and side walks to the overpass which will sit on top of the white plastic so that I can pull it off as necessary to clean the tracks underneath.
I have also finalized the structure layout for the "Chemical Plant". I really need to work on the photo back drop for this area. I will compose it in photoshop and then have it printed at Office Max.
