40+ Foot Suspension Bridge

We decided to build a suspension bridge to get to one of the islands. Got tired of walking over the fallen tree. It turned out great and has held up great as well. The total cost was around $400 - to $500. I've had multiple adults (over 700lbs) at one time crossing with no problem. I'm sure it can hold well above that. Can't wait to build another one!

That's cool, we built the da vinci bridge. We recently got metal cables a fiber optic cable company dumped on our land, might be a good idea for us to utilize it by making a bridge.

Thank you for showing the estimated cost. I never understand why people don't tell you cost estimates like it's some kind of secret. I'm definitely doing this in our backyard. Thank you so much.

Great job. One item of concern you may want to review and others may consider avoiding is the use of copper fittings with steel cable. Using dissimilar metals can cause premature corrosion.

I think this is great inspiration. If you do it again. you will want to avoid putting modern PT wood into concrete. The new treatment chemicals are leached out by the lime of the concrete, and that causes rot. Building codes are being revised to prevent the practice. You could instead put a concrete column below the frost line, and use a steel mounting post. Then tension the other side with a cable anchor, to more concrete in the ground. Again, great job. Nobody is going to die falling fro that low height if those posts fail. Enjoy.

Thank you for making this video. This seems like a straight forward process. I can’t wait to get started on mine!

Almost a year later and I've now completed our project just in time for spring. I made one significant mistake. The clamps must be saddled on the live side and equally spaced. I had to learn the expression 'don't saddle a dead horse'. Thankfully, I was able to determine the mistake before I or anyone else walked on it. After securing properly the cable became very solid. I was also advised the clamps are supposed to be torqued to manufacturer recommended specs but I didn't bother with that and instead went until they were very tight without bending the cable.

U did a really nice clean looking job! I'm going to do the exact same thing on my property. I have a 75 foot span across my river. I seen that you used 3/8 wire cable, but I think I should probably go with 1/2 wire cable. Great job!

Thank you for a great video I looked at many to keep it simple you did a great job I'm going to duplicate your bridge in North Florida is a creek on the property

Joe hey just wanted to check in and see how this held up and what would you change if you could do it again?

[DaveV]

1/Where do the cable thimbles attach too ? Also how many are needed please ?

[KWattmizer]

Hi Joe, what diameter size cable did you use and the amount of groups and also the gauge size please for your neat 40ft bridge it is beautiful !!

How does it handle a flood? On my creek there is alot of deadfall that i fear would pile up on the bridge, was wondering if you have encountered that scenario

[travisjohn]

I'm curious how much those posts have sagged 2 years later ? Guessing quite a bit.

[markpfeifer]

Man, I hope those vertical end posts are deep and their concrete footings are large. They are taking a lot of load.

[TheKaveman]

Just wondering how far apart your posts are? Looks about 4 feet

[robertjones]

In the middle of my own bridge project right now…. About to rig the cables. I’m worried I made the width of the bridge too wide at 3 and 1/2 feet from cable to cable…so you mind if I ask how wide is your bridge?

[jlydon]

How are the decking screws holding up with movement?

[heiheiheiiii]

Hi! Thanks for making this video.
I'm making a bridge too

What kind of cable (how thick) did you use

What other hard ware do I have to get?

If you don't mind could you give me a materials list?

Thanks so much!!

I need to construct two or three of these on my land over some ravines that are about 20 to 30 feet deep so I am posting this as an open question for anyone who can respond with useful information. I need to size my bridges not just for foot traffic but to be wide and strong enough for a typical ATV with a rider. My largest ATV with me and gear aboard is about 1, 000 pounds, or slightly over. I know I will need maybe 6 x6 or even 8 x 8 end posts on each end. And I plan to anchor turn buckled cables at the top of each end post pulling back against the posts to help stabilize the foot bridge when it is under load.

But what size cable, what size decking, runners, and fittings, etc. do I need to consider? Has anyone built a suspension bridge like this that they have tested with ATV travel over it? This is to be an upcoming summer project so any help would be greatly appreciated. I understand the cost will be more but it is essential I find a way to easily travel across these ravines.
