I thought it would be fun to share the basics of this design as an Instructable for people who have enough skill to be able to take the information and work with it. And as we do in our book, we recommend having your specific design approved by an engineer just to be on the safe side. So here you go! We also have a blog with a fairly recent materials price list, hints and tips, and other projects. Link is at the end of this Instructable. PS Thank you all so much for the votes in the Outdoors Contest!

February 25, was not a good day for our suspension bridge. A snowstorm hit that weekend with inches of wet, heavy snow, and trees started falling everywhere. But alas, one big alder tree snapped and landed on one of the bridge posts, breaking it in half.
In a suspension bridge, the traffic-carrying deck is supported by a series of wire ropes that hang from massive cables draped between tall towers. The Akashi Kaikyo Bridge in Japan, which was completed in , contains the world's longest suspension span distance between support towers —6, ft 1, m ; the entire bridge, including the portions between the towers and the shores, totals nearly 2. A century earlier, construction of the Brooklyn Bridge, with a span of 1, ft m took 14 years and resulted in the loss of 27 lives. Suspension bridges are one of the earliest types devised by man.
