Whether you have a popsicle stick bridge, balsa bridge, toothpick bridge or other type of model bridge, these testing tips will give you a jump start and help you make an informed decision on how to test your bridge.

How to Build a Model Bridge

Building a model bridge is one of the most rewarding hobbies I have done in my entire life . I have learned a ton about working with wood and tools. I have also learned the basics in bridge engineering, and have a greater appreciation for real bridges. Model bridge building has also given me a originative outlet that I can share with others. Not only does it give me something fun to do, I can show off my creations and attest to their abilities.

Model Bridge Kit

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

5 Steps to Building a Model Bridge

This ebook, 5 Steps to Building a Model Bridge, answers the most common questions people have about building bridges.

Video: Build A Model Bridge

This is the absolute best video I have seen about building model bridges. Roy Coleman, the founder of the International Bridge Building Contest, gives a very informative presentation in this video. The presentation is over an hour long. He shows how to build a bridge from scratch. He is gearing his video towards the…

Old Model Bridge Trusses

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

First attempt at a DIY model bridge

It’s taken me just under 48 hours to get this far. Although i wouldn’t say its completely finished.. it’s a good as. I might just polish it off with a lick of paint and other aesthetically pleasing type things. As you can see, I’ve modelled it on the Pratt Truss. Although, I didn’t do any “real” plans, just rough drawings

Model Bridge Truss Design Software

No Longer Available I am always on the look out for good software to help design model bridges. My latest find, Dr. Software, is a series of programs that allow you to customize a design, put a load on it, and see what happens. Dr. Truss comes in 2D and 3D options. You can also get Dr. Beam, which allows you to word with a beam and not a truss. The pictures in this post are from Dr. Truss 2D. […]

Model Covered Bridge

Garrett- Jobs well done – interesting site and information! We built a 1/8″ scale model bridge just like the bridges we build for production. We successfully loaded it with 345 pounds with the weight being distributed all the way across the middle. Do you know of a formula where we can figure out that weight capacity for our full scale bridge? We have contacted 3 different engineers in our area who don’t have access to such information. Thank you for […]

Popsicle Stick Suspension Bridge

I have always wanted to build a model suspension bridge, and finally I have finished one. This is a popsicle stick suspension bridge. I created it from scratch, coming up with the design on my own. After testing it to failure I learned quite a bit about how suspension bridges react to loads. This model suspension bridge uses popsicle sticks as the main building material. The decking is cardboard, and the “cables” are 550 parachute cord (military surplus)
