I have a creek that cuts the property in half. The bed of the creek is 35-40 feet wide. it handles large volumes of water during rain events but not much more than a stream any other time. A bridge is not an option. Each bank slopes gradually so to have a bridge high enough to allow water and debris to pass would have to be 100 feet or more.

I'm looking for ideas on a low water crossing. A few times a year a tractor will cross but mainly atv or 4x4 truck. I considered logging mats fastened together with a and driving pilings on the 4 corners to keep it anchored. Not sure how long they would last submerged in water and sand. Another option is to do the same with cross ties. 80 of them laid out and anchored the same way. I'm thinking they may last 3-5 years before rot starts to deteriorate them.

Rip rap rock was another thought but that would probably run 3k or more and over time they would all wash down stream.

Shot rock and make a shallow water crossing.

Anything else will wash away.

This may be a plan for in the future but will be very expensive so we need time to save up for it. Pretty sure this too will eventually wash away

its going to be very tough if trying to do it cheaply. You said something about 3k and that isn't much when trying to do something like cross a large creek.

What do you mean by "large volumes of water? 35-40 feet wide and 2 feet deep? Rip rap will move certainly, and I'm not an engineer but unless that water is really rushing through there I'd try that first.

Honestly, throw a couple pieces of rip rap in there and see what happens over the next couple of months. Then proceed from there.

Why do you have to cross the creek in that spot? May be cheaper to move your road some to a narrower spot.

You find an old single wide trailer and use the frame as a bridge.

He said it would have to be 100 feet or more to span.

I'm talking 10-12' deep and full size trees and root balls coming down stream during big rain events.

Yea that's a pretty obvious thought but it is the only place. Is on the northern property line and to the south there is a feeder creek that comes in so that would require two crossings.

There's nothing cheap that's gonna handle a creek this size. I've seen steel grating wash away in that kind of current.

That said we have an old creek crossing that was made by just laying cross ties years ago. They haven't rotted at all and are still in place and have been there since I was a kid. No doubt a strong current could take them out but they handle the occasional 3-4 ft gully washer every now and then.

Get some 1 1/2" serrated bar grating and anchor it with some rebar.

We've done this. We've also used an old flat bed trailer.

Our crossing are similar. We just put the bridge from sandbar to bank. We usually have to replace them every 6 or 7 years though. Some setups last longer than others.

Why do you need anything at all on the bottom? We have a similar crossing on the creek that cuts our property in half. We've had a bulldozer cut both banks and pour rip rap there but the sand in the creek is hardpacked enough where it won't stick a tractor or truck. The rip rap up the banks provides traction at the incline.
