HO Scale 145 ft Steel Arched Truss Bridge

thingiverse

I designed this bridge from a MR Magazine image attached to this message. To build it, you simply need to print two of each component, which will fit on a 10" bed. The components are mainly self-aligning. The upper trusses come out flat but will naturally bend to follow the curve of the bridge. A detailed set of instructions is included with the design. I've also added bridge rail guardrails for extra protection. My preferred track size is Peco Code 83. The ties on this track fit perfectly into the guides on the bridge, while the rail guardrails snap securely into place between the ties. For easier assembly, it's recommended to paint the different color sections before putting everything together.
