Welcome to the Douglas Butler bridge book, explaining the Technical
Drawings of movable bridges across the country, as well as numerous picture photos
of bascule, lift and swing bridges. I researched the Inventors of these drawbridges over the past seven years. I have discussed
with some bridge workers knowledgeable about the different types of movable bridges. This Article will show examples of some
movable bridges, and how they operate. It is not just an art, but also an educational understanding of how the bridges work.
I hope that you'll enjoy the information and learn from my book. Thank you.
You can email me at drawbridges@ lycos.com, or view a sample
of the technical drawings of movable bridges at http://drawbridges.tripod.com. For a complete look at my drawings, visit my site at http://www.flickr.com/photos/94273918@N06/ , which shows the variety of movable bridges of the United States, Canada and the Inventors.
