Why a good gravel drive starts with a culvert
Water is what ruins a drive — not traffic. Every rut you've ever cussed started as water that had nowhere to go, so it went through your rock instead of under it.

A culvert set at the low point moves runoff under the road. Pair that with a crowned finish — higher in the middle so rain sheds to the sides — and the same gravel that washes out in two years will hold for ten. It's the least glamorous money you'll spend on a drive and the best.
If your existing drive keeps rutting in the same spot, that spot is telling you where the culvert should have gone. We can usually fix it without rebuilding the whole road.
