Jerry Meyers How did you make the arc??????

Custom Home Planning Center I do arched garden bridges with 3/4" pressure trt. plywood. Laminate, glue and screw the plywood after you've cut the plywood to the height and curve you need for the bridge truss. Lengths under 8' are best as longer takes lapping joints to create a stable bridge truss. You then use 3/8 Trt. plywood laminated for the bridge deck. I cover the deck with water proof membrane roofing and add the appearance deck. (wood, concrete, plaster or stone keeping in mind the higher the arch the more you should use a rougher non slip material.)
