The Bridges resource has been re-written. There is no longer a section on materials (though it is hoped here will be a brand new resource looking at all building materials - not jus realted to bridges - in the near future).
This website is an extract from an ebook written for children. The complete text, which also includes sections on other ways of crossing obstacles, can be purchased from Amazon's Kindle store.
