I’ve got a spot that I need to fix a crossing to establish a perimeter road/trail in the woods. The spot drains about 60 acres. It’ll be primarily for ATV traffic, but I may want to maintain it for dry weather truck traffic too. Pretty sure a 36” pipe will suffice from the charts I’ve looked at. Whole watershed is wooded with moderate slopes.

Is 20 feet long enough? Seems like it would be. Longer is better but it comes at a cost. Any other advice from folks that have done this before? This is a ravine requiring quite a bit of dirt moving, oddly it drains a relatively small area, though. Thanks in advance.

Length depends on depth of hole.

Thanks. That’s gonna push it longer then.

I have access to some 40’ joints if you need. May be 42” though, I can see what we have left in our yard. This is steel pipe for kinda cheap.

Dealing with my own land through trial and error process I will tell you that never do a culvert if you can do a bridge.

I don’t know where you are in the world but with the silty loam soil we have here, as soon as I scratch the surface of the ground somewhere it starts eroding. I’ve tried what feels like every failing method. Best advice I have is do not break ground on a slope that drains water

Thanks. I’ve got plenty of experience with erosion in loess soil along the bluffs of SW MS too. Agree this is not ideal. Bridge approaches would probably still be prone to erosion issues, though. I could show you plenty of abandoned bridges in similar geology (that drain much more acreage).

This spot is just too wide for a flatbed to make it across. What would a bridge cost? $30k? More?

I tried the culvert route when I first bought my place. Didn’t work. Finally purchased an old trailer frame and put new boards in it.

Much easier to take care of.

I own 1800 acres of hunting property

1-With longer pipe, you can have gradual slope, which will grow grass..you can cut… will stop erosion.shorter pipe with steep sides will erode, especially red dirt
2- get biggest circumference you can… one flood event and you are screwed.

If that bad of an erosion problem why not use an “underwater “ bridge of 3-4” rip rap? Works well in some areas. May not in yours

if it's just atv, no, but for vehicles and tractors, if you're putting in bulkheads, etc., yes it can easily hit $30k and keep going.

As mentioned, length depends on other factors, but i can tell you that a 20 ft. stick is rarely long enough, especially for a pickup.

Absolutely. We reset and/or replaced 2 large 96" steel culverts so many times at my grandfathers we lost count. About 12 years ago a gas company came through and put a bridge across the creek. 2 of the worst floods ever endured have happened in the last 10 years and the bridge was not damaged at all.

What was happening? Heavy rainfall events washing the pipe away? Or water running down the approach causing issues? How much acreage was draining to this spot? “Creek” says bridge to me, too.

I’m starting on a low water creek crossing tomorrow. I’ll try to post some pictures.

We successfully built two "bridges" using 40 foot shipping containers in SW MS. Crossed many times with ATVs, a tractor and regular trucks. Makes a great escape when a sudden storm hits.

Worth a think...
