You mentioned that the impetus for this project was the cost of buying the brick. Did you track the cost of your solution? Was it substantially cheaper?I would like to install a truck friendly access to my side yard, but not go through the appeal process to get approval for another driveway. I like to get deliveries of firewood, wood chips and leaves but have had the trucks get mired down in mud if there has been rain.
