This is a 76' suspension bridge across an arm of the pond on my property. It is built from treated dimensional lumber and galvanized wire rope with a small amount of plated 3/16" proof coil chain. Oh, and lots of bolts and screws!
I needed the bridge to more directly connect the meadow below my house with my picnic grounds - which were on the other side of the sometimes-arm-of -the-pond, sometimes-nearly-impassable-ravine.
This is the best resource I found online for building this bridge:http://www.trailstobuild.com/Articles/PochuckBridgeEngineeringArticle/Pochuck%20Quagmire%20Bridge.htm
The bridge cost about $4000 to build and took several hundred hours of labor and thought.
Not that the thought wasn't labor, too!I want to thank all of you that voted for me in the Woodworking Contest. I ended up 6th in the voting! Now for the judging!
Update - runner up in the Woodworking contest. I got a t-shirt - I'm happy! :)
