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:
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! :)
