Great project. I've been considering doing something like this in our backyard for my 12 year old son from tree to tree. How did you attach the cable to the poles?
My wife has me building one of these across our creek. Did you use 2x6 cross braces and 2x6 long treads? How much space between cross braces? Did I hear you say 24"? How's it holding up after 3 years?
The way you layed your runners is perfect for keeping some numb nuts from trying to stand /walk on the outside ends of the boards where he would quickly gain more respect for Sir Issac Newton.
I am considering building a semi-covered circular platform near the top of a giant oak tree in the backyard and connecting it to the house via the deck and several suspension bridges. The first span would lead to a smaller oak about 100 feet from the deck. That span would terminate at a small 6'x6' landing in a smaller oak (36" diameter x 80' height). From that landing another bridge span approximately 40 feet to yet another small landing in another smaller oak. Then one final span of about 60 feet to a larger oak tree (48" diameter x 80 feet high) terminating at a platform 12 x 12 feet, or 12 foot circular (not sure yet). Due to the lay of the land and keeping each suspension bridge at about the same height this would place the 12x12' large platform about 60 feet off the ground. I am already thinking of an add-on small staircase leading from the 12'x12' platform to a smaller 6'x6' platform about ten feet higher up in the tree. The smaller platform would be located within some larger limbs off to one side of the larger platform below and not directly overhead. I think it would be cool as h*ll to grab a cup of coffee in the early morning just prior to sunrise and take a stroll across three rope bridges to a comfortable chair located 60 feet in the tree tops. But first I want to build a secret room about 12'x 18' directly under the swimming pool. The access door to be hidden within the pool filtration room behind the pumps, filters, heater and electrical room. The electricity to the hidden room will tie into the main breaker box in the house bypassing any circuit breakers there. The breakers for the room to be located in the room itself. Anyone looking at the main breaker box in the house would not be able to easily find the hidden power line. Only the home's main breaker could break the connection to the hidden room/ storm shelter/ bunker, etc. I also plan to run electricity, water, and internet to each platform in the trees. Across the deck and hand railings I want to install LED lighting similar to the Icecicle lighting used at Christmas time. My final build will be a rock lined tunnel leading to a hidden access under the house and then off into the woods where I will have a secret entrance/exit door. Isn't this what you do after retiring at age 49? Buy/build all the cool stuff I dreamed of doing all those years working. After my death some lucky home buyer will find all my hidden tunnels and rooms and think how cool his house really is.
The cables were not under tension when building bridge. In fact, they had a lot of slack to allow the bridge to move. The cables wrapped around the posts and cable clamps were used to form loops at each end. Technically, the whole bridge could be lifted up over the posts, but the weight prevents it.
It’s been a few years since this project, how’s it holding up
August 2019....the bridge is still as good as new.
Great project. I've been considering doing something like this in our backyard for my 12 year old son from tree to tree. How did you attach the cable to the poles?
We used an auger to dig the holes for the uprights. Also used cable clamps to hook the cable to the uprights.
how much did this cost, and where did you get the materials?
My wife has me building one of these across our creek. Did you use 2x6 cross braces and 2x6 long treads? How much space between cross braces? Did I hear you say 24"?
How's it holding up after 3 years?
yes,, I heard him say "2 feet"
Where did you get the cable?
Is that treated lumber? Approx cost?
How has she held up?
do you have a parts list
mainly what you used to connect the wire rope to the rail road poles
How much did this cost

made that look easy...
nice bridge! could you drive a small seat down mower across this bridge?
14500 lb cables??
Yes. Farmtek.com. Search under building materials then cables.

how to tension the steel cable?
The cables were not under tension when building bridge. In fact, they had a lot of slack to allow the bridge to move. The cables wrapped around the posts and cable clamps were used to form loops at each end. Technically, the whole bridge could be lifted up over the posts, but the weight prevents it.
Bridge is still as good as new.
