Here are the video results from the Bates Tech Balsa Wood Bridge Competition 2011. This simple video footage of the competition makes for a good learning opportunity. This video includes a variety of designs that are interesting to observe if you are looking to build a balsa wood bridge.

A very nice looking Balsa wood bridge sent in from one of my readers. This bridge uses gussets and pin joints and spans 18 inches.

I like this video because it is very systematic and well documented. The video shows a Balsa wood bridge built for a statics project. The bridge ended up with an efficiency score of 514.

Here is the model bridge featured in my ebook, 5 Steps to Building a Model Bridge. This is the bridge seen in the photos of the step by step process of bridge construction. This video shows the last bit of the testing process in which the bridge comes to an explosive end

Here is a balsa wood bridge being tested to failure. You can tell how it breaks, which is pretty cool

Here is a bridge using the K truss design made from Balsa wood. This bridges uses a combination of end and lap joints. You can see that where the slanted members of each K join together at the vertical member, there is an end joint. At the top and bottom chords, the joint is a [...]

Here is the Science Olympiad bridge J.C. Booth built for the Georgia State Tournament in 2005. I don’t remember exactly what place it got, but am pretty sure in placed in the top 3. This bridges uses the typical design for that year, with slight modifications

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

Hey guys it’s me again, First Timer. Taking the critiques you guys gave, I rebuilt the bridge. This was going to a county Science Fair which I think is pretty cool considering I started learning about bridges about 2 months ago. The specs of the bridge are

Hello everybody my name is First Timer and I had to make a balsa wood bridge with theses specs: 40.5 cm long, 11-12 cm wide 13-25 cm high, must have a span of 26 cm, peek of the span must be at least 9 cm, and this bridge could weigh no more than 16 grams
