Purchase the Arched Garden Footbridge Woodworking Plan, including step-by-step instructions, detailed illustrations, and a complete materials list. For more outdoor woodworking plans, visit the Outdoor Furniture and Structure Plans section in the WOOD Store. This arched footbridge can be built out of either Western Red Cedar or Redwood, using 2x4s or 2x6s for the floor planks and 2x12s for the support stringers. Find the center of the stringer (2 x 12), as shown above in the bridge plan diagram, and determine the amount of arch you want by tracing the arch at the bottom with a pencil as shown on the image to the left.
You should leave 15 to 18 inches from the end of the boards on the bottom cut so as to have plenty of support on the stringers for the weight of the bridge as shown on the image to the right.
One way to determine the amount of arch is to use a tack and string to make the arch or use a compass or just carefully free-hand trace the arch.
After you have cut the bottom piece from the stringer you need to make an arched cut on the top. After cutting the floor planks, the next step would be to place the 2 support arched stringers 32 inches apart straight and level.
If you take your time and have modest woodworking skills you can easily build this type of bridge. It will take some practice for you to get the proper arch needed for your own particular footbridge. Be careful not to make your arch too high for safety concerns especially if you live in an area where you get rain or snow on your bridge or people may slip and fall because of the steep slope.
Place the first plank square at the end of the bridge and overhanging the end of the stringer by 2 inches.
Space each plank by using a carpenters pencil between each plank to get an even space between each floor plank. You could also cut out the top arch by tracing an arch across the top of the stringer with a pencil and cutting it out with a jig saw.
