Creek crossing construction concepts

[crappyice]

So what are some suggestions for making an ATV crossing in a spot like this using whatever is around (cedar pines, piles of shale, decent large rocks). The creek is about 10’ across.

 

 

 

Any pics of what you have out there already would be helpful

@Culvercreek hunt club helped me build a bridge for such a crossing.  Used a 14” diameter oak to span both sides (approx 15’ span).   Then used pressure treated 2x10 spaced out for the bridge.   Worked well.  Dig out where cross pieces sit and put 2x10 pressure treated below so tree is not sitting on dirt.  Used chainsaw to flatten cross pieces as needed.   The oak is freaking heavy!

I will say my creek bed was 5’ below so no fear of washout.

Deleted - See its ATV.  Im with Moog if you can get pressure treated in there thats the way to go. Lot of work to do otherwise that prob wont last.   Dont want to block the water cause it will just either move, wear away or go around if you just drop trees and rocks etc, so that means over it and straight cut stuff is gonna be a lot easier

Culver calculated the load and it took at least 6x6” pressure treated for cross members and even that was questionable.  My recollection is that we would need 3 6x6 15’ long. .   That’s why we used the big oak tree.

Building a culvert is another option but it’s a big pipe you will need.

As long as it never floods you're in good shape with whats been mentioned.

Leave spacing between 2x10 for snow and water.  I spaced them 4” apart.   I also built up some guardrails  about 6” high with 4x4” just so ATV wouldn’t accidentally veer off.    My daughter got a bit nervous without the guardrails as it was 5’ wide for a 4’ wide ATV.  Seems plenty but not a lot of extra room.

That’s the big fear.  Wasn’t so much for us as our creek never gets near the height of the top of the bank.

I put one over a 5' wide creek - I used 3 8' PT 4X4's, running the two outside 4x4's in line where the atv tires would travel across. I then used deck board. While it works, I would have preferred 2x10's as Moog explained. It is just what I had on hand. Guardrails are also must in my opinion.

I also did not have to worry about flooding during the construction.

Good deal...any pics moog? I’m a visual learner!

My buddy has a solid bridge with concrete blocks on both sides with I beams and rail road ties and it's no match for a good rain storm ,I've helped him wrangle rail road ties and pull them back up stream a couple times ,it sucks.

Can’t find a pic but will post one when I am out there next.  10” creek will be a big span.  You will need sturdy cross members.

Get your hands on two lengths of train track, thats the base for the bridge at my buddys place. @G-Man is your guy!

[Culvercreek hunt club]

Here is Moog's bridge.  That was a LONG day...lol

 

Might want to "log cabin an abutment on each side and then use logs to span. It will help with the wash outs.

I found them.

I have found that bolting together 2- 2x8's standing vertical is stronger than a 4x4 for the lengthwise span. Then used  2x6's crosswise. Left an edge to keep me from sliding off with my mower.

Save yourself a ton of time and just build a small ramp with dirt on both sides. 10 feet is nothing to clear with a little speed.

How about dragging a deer?

He only targets does, so 2 guys can easily throw one across.

Culver was the engineer.  I was just labor.   It’s sold and was a lot of work.

See-you, as someone who actually hunts and harvests, would understand.

I have a similar crossing that I’d like to put in and was thinking about using telephone poles as the main support. Has anyone used them for this type of application?

This is one I built a couple years ago, I’ve seen people use a semi flatbed trailer to span bigger creeks
