I built one of these for our only driveway through a swamp on a piece of land I own. You wouldnt believe what proper drainage can do to swampy ground.View attachment 770222
Wet wood roads? This is what I was picturing in my mind reading your post. Corduroy roads
I did logs, dug becids and covered the logs in dirt then road fabric and 4-8in of stone. I had 20klb of stone truck driving over it within a month.
