Manilla File Folder Bridge

By on July 24, 2007 -- Modified on December 9, 2017

Built by Bill H.

Here is the email Bill sent me:
I started making bridges about a year ago and have pictures to share with you. For the first bridge I used a set of plans that I found free on the internet from a guy who was in the army. The bridge plans were designed to be made 100% from manilla folder paper. The plans were to fold the manilla cardboard into the different post diameters and use them to make the trusses.

I decided to use dowels from my local Lowe’s instead. However, I did use the manilla cardboard to reinforce some of the joints and to give the bridge a real look.

You can find the plans for this bridge here:
Manilla File Folder Bridge

This truss bridge uses the Pratt truss model for its design. The Pratt truss is one of my favorites because the longer diagonal members are in tension. This allows the shorter vertical pieces to be in compression.
