The Pratt Truss design has a long history of being strong and efficient. It became very popular when engineers started using iron to build bridges for railways. This model popsicle bridge is highly efficient and fun to build. The Pratt Truss is one of my personal favorites and I take pride in how well this model bridge performs.

Full scale blueprints and detailed building instructions show you every step of the building process from start to finish. Pictures are included for every step and helpful hints are sprinkled throughout the instructions. You will also receive a one page document which explains some things you need to know before building the bridge, as well as what to do with your popsicle bridge after it is completed.
