Design the path for the road and mark it with chalk or marking paint.
Dig out the area, removing the topsoil from the paved area with a shovel. Rake the area to ensure the ground is level after digging. Tap down the dirt using a large, metal tapper.
Hammer a stake into the ground every 18 inches to 24 inches along the road with the stakes 1 inch from the edge of the road area.
Slide 1-inch by 4-inch lengths of wood between the dug-out path and the stakes.
Hammer gently to ensure the lumber will stay in place. Secure to the stakes with nails, if necessary. You are now ready to pour concrete or asphalt into the mold.
