This is a very simple yet elegant looking bridge that I built over Christmas break. This bridge spanned 16 inches and was made from 48 popsicle sticks. It held 75 pounds, which was right at what I was expecting.

I found pictures of some old trusses I built for Science Olympiad bridges. Most of these were built in the 2003-2004 school year. I thought I would post them to give examples of how these trusses could be used in model bridges

This kit is actually one of my first introductions to building model bridges. My mother bought this for me one year, thinking that I might like to build a model bridge kit. This bridge building kit from Amazon actually has three different bridges. It comes with all the supplies you need to build a suspension bridge, a truss bridge, and an arch bridge. All of these combined make this kit an excellent gift idea, or something you can build just for fun

This is an older bridge I came across when browsing through my old Science Olympiad photos. I used both Balsa and Basswood to build this bridge. This bridge was part of my design process which ended up with my SO winning bridge in 2004

I just completed a new toothpick bridge that’s quite different than my last one. It’s an arch made from curved trusses, formed once again with toothpicks and wood glue. This one won’t be tested either (sorry!) because it was made for a friend who creates custom action figure dioramas. But I designed the bridge to have the highest ratio of maximum load to bridge weight and some ad hoc tests made me pretty optimistic

These are the photos of a popsicle bridge that I made for a bridge building contest at my university in Spain. The weight of the bridge was 3.9kg, and the bridge held 700kg without breaking. This gives it an efficiency score of 180. The dimensions of underneath the arc are 90cm x 45cm.
