I designed this bridge from a MR Magazine image (attached). You basically print (2) of each component each will fit on a 10" bed. The components are mostly self locating. The upper trusses are printed flat but will bend to align with the curve of the bridge. I included a page of instructions for this. I also included bridge rail guardrails. The track I use is Peco Code 83. The ties will fit into the guides on the bridge, and the rail guardrails will snap in between the ties. I recommend painting the different color sections before assembly to reduce the amount of masking.
