I modeled this bridge from photos I took of the South Fork Snosqualmie River Bridge near Snosqualmie, WA. It was modeled in Blender.
This was my first upload at CGTRADER. I picked 3D print model. I've never did 3D printing. Seems this file might be challenging for that. Seems you'd have to print separate parts and glue together. If you need any other files please let me know.
