Assemble the three pairs of double 2x8 beams before lifting them onto the top of the posts. For each pair, cut two 7½-inch-square pieces of ½-inch-thick pressure-treated plywood. Screw the plywood plates to the bottom edge of two 2x8s with galvanized decking screws. Carefully position the plywood plates so they align with the posts.
