Need to bridge or culvert a creek on my property
Hello All,
What a great site! I just ran across it & registered immediately. Help!
My current dilemma is how to get my tractor across the creek into the woods for firewood, mowing, etc. (Our 'new' neighbor will not let us use the access enjoyed by generations to cross the creek)
The banks are sloped about 50-60 degrees, with a 9' elevation down to the surface of the water. To get to frost depth for footings, the span needs to be 38'. If something could be just laid on the ground, it reduces the span to 30'+/-
Re: Need to bridge or culvert a creek on my property
You did not say how deep it is. But the less expensive way to do it is to cut the banks down and make some sort of ford where you can just drive across it. Culverts and brides can get expensive in a hurry.
It so nice to have such understanding new neighbors. Hope you get to return the favor soon.
Re: Need to bridge or culvert a creek on my property
Yeah, my wonderful neighbors....The creek is only 1-2 feet deep, maybe gets to 3'-4' in the Spring. The creekbed is very unstable; I wouldn't take my new Kubota in there....Anyway,the creek is at the rear of the backyard where it would be impossible to make any kind of cut. A 54" culvert, rip rap, sloped headwall, etc is required by the county; that's why I'm looking for something cheap n easy to bridge the creek. I thought maybe bridging it solid with used telephone poles and planking it with 3" roughsawn oak...

Well the telephone poles and planking would be my second recommendation. Not sure how much poles cost or if you could get by with used ones from the power company.
The danger of that setup is sliding of the sides. I think I would want some sort of side rails maybe railroad ties along each side to keep it (tractor) on the bridge.

On this one the span is such it may require some serious design considerations.
How will you you get the abutments in place on the other side of the creek?
Is there a possibility to drive H piles for the abutments?
The culvert may become cost effective when all factors are taken into consideration.

Re: Need to bridge or culvert a creek on my property
Personally, I'd probably go the culvert route. I put in a 42" culvert across a drainage creek 2 yrs ago. It replaced a wooden foot bridge so I could take tractors/trucks across the 15-20 wide creek. A 20' long 42" culvert cost me $400 by buying it through the County. Sand backfill and gravel topping cost another $400 or so. So I'd figure you're looking at somewhere around $1000 for material to do yours with a culvert.
For a bridge, I think the poles would work for occasional use traffic, but it may be a little "springy" for a 30' span. Of course, you can always stiffen it up by laying more poles. If you can't get poles, maybe just fell a few trees in your woods if you've plenty to spare A proper bridge with concrete abutment and steel I-beams would be cost prohibitive and probably convince you to go the culvert route.
If you use poles or trees, you'll probably end up with SOME maintenance over the years, but a culvert will require very, very little, if any at all.
Re: Need to bridge or culvert a creek on my property
Wow. Thanks you guys for all the input. The county here(Genesee) pretty much dictated the spec-54"minimum 22' culvert($2000) A good culvert would be perfect, but total material runs around $5k. That's why I'm looking for other ideas. I want to be able to pull trailers of green firewood over it with a small tractor. Timber trusses? "covered bridge"?

Jim, Right you are! "Culverts and brides can get expensive in a hurry.
Bridges too get expensive but I think brides can be a front runner.

Re: Need to bridge or culvert a creek on my property
Wow, 5 times the price I paid for a culvert that is just 12" bigger in diameter!! I checked with the place I got mine and the price of steel HAS driven prices out of sight in the last 2 years. Plus, the 54" is made of 10ga steel, mine was 14 ga. In fact, I paid extra (5%) because I wanted a "low profile" culvert pipe that looks kind of squashed but has the same flow opening as a round one. Called a "Pipe Arch". Are you in Genesse County in Michigan? Did you get the price from the County? I know I got a better deal because I ordered it through them (St. Clair County in Michigan).
"Timber Trusses" & "Covered bridge" sound pricey, too, especially when you talk about "trailers of green firewood over it with a small tractor". How "small" a tractor? What does it weigh? I'd be afraid to build anything with a 30' span out of wood to carry any significant weight that I designed myself. [img]/forums/images/icons/tongue.gif[/img]

What does the county have to do with it?
It's on private property isn't it?
