Here I have complied what I believe to be the best list of websites that you will find useful. All of them have relevant model structure, bridge and tower information, some sell balsa and basswood, and others contain useful tips. Some of these sites have a specific competition or goal in mind, but you can always take the principles and adapt them to your needs.

hello…i’ve built a couple of bridge with teriyaki sticks…i’m interested to see other modelers images, can’t find any in Google’s Images or any other known resource…can you help me? thank you
Do you have any idea where I could buy a large set of foam or plastic blocks that would be used to build an arch bridge? I want it to be as large as possible, up to 5 or 6 feet tall even. I haven’t found anything like it on the internet, yet.
Sarah, I don’t fully understand what you need. Are you needing something to bend wood on for the arch bridge? What exactly are the foam or plastic blocks going to be used for?
Thank you stopping by my blog the other day (tuckerteacher.edublogs.org), and commenting on my students’ bridges! Your website is very cool, and has so much useful information that I know will be useful for future model bridge building projects!
Where can I downlond the west point bridge designer?

Hello! I’ve been a long time reader, but am having trouble viewing your site in Opera today. Did you update something?
I would ask you to include us in your list of vendors of balsa wood. Lonestar Balsa is the resurrection of Lonestar Models after the devastating fire in 2007. We have been supplying balsa to modelers for well over 30 years. We can provide all balsa needs for bridge builders.
Thanks for your consideration.
