We are unable to obtain 2 X 8 KD pine for the bridge. No one in their right mind will market this type of material for construction in Hawaii. We have a severe Formosan ground termite problem and anything that is not treated is eaten. We have exhausted our search for pine in the islands. Our only alternative at this time is Hi-Bor pressure treated 2 X 8s or we laminate pine shelving boards together. The Hi-Bor lumber is wet and ridiculously heavy compared to kiln dried pine. Our concern is the extra weight that will affect balance, inertial forces and weight distribution. Any ideas? Can we laminate AC grade plywood instead for comparable results? Please help us on this insect infested island!
