Pratt Popsicle Bridge

Description

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.
