Toothpick Suspension Bridge
I just finished this bridge a few days ago after working on it on and off for 3 months. It’s a cable stayed bridge design made with standard round toothpicks and wood glue.

Hi, I just wanted to share the excitement…by using ideas from your website (recommended by my son’s Cub Scout leader) my son Jackson and I were able to build a Popsicle bridge with approximately 125 sticks.

It’s building different bridge designs with K-NEX, Erector Sets, and/or LEGOs. Most of you probably own one or more of the following and it really helps practicing basic truss design

Coolest Popsicle Bridge
