We have some acreage on the back side of our property that's all grown up. DH can't get to it with his bushhog due to a drainage ditch he can't get across with the tractor. Actually, here in the south, we call it a branch. It's a wet weather stream. At the present time, it's dry. It's approx. 3' deep and maybe 5' across. We only want a bridge/culvert or whatever that will get the tractor and 4-wheelers across, but not just one time use though. There'll be no need to cross with vehicles. Of course, we don't want to spend a bundle for something that will work, though willing to pay a little and willing to do the work ourselves.
