Garden bridge construction instructions

Garden bridges serve many purposes. You can build your own garden bridge that offers a walkway over a stream or thin pond on your property. You can also use a garden bridge as functional decoration for your garden landscape. You can even join two separate little gardens and add stones to a path. Building your own garden bridge can be less expensive than hiring a professional carpenter to build one for you.

  • Fit 2 8 feet by 8 to a 2 by 8 36 “end. Align the end of the 8-foot board so that it is flush with the corner end of the 36-inch board. Position the top of the leg 8 to the face of the inch 36. Fix with two 2-inch screws at the top and bottom edge, from the opposite side of the 36 inch through the foot 8.
  • Attach the second 36-inch gasket to the bottom of the 8-foot gasket, in the same way as the top.
  • Place a second 8-foot board between the two 36-inch boards, in the center of the mark you have made and attach. Place a third 8-foot board at the other end of the 36-inch boards, making sure they are flush.
  • Drill three 5/32 inch holes through the top and bottom 36-inch joints on the 8-foot boards. The holes should be in a straight line. Secure the screws and washers in each hole and adjust with the ratchet and 9/16 inch socket.

Guard rails

  • Use the Plaza Carpenter to mark and cut the corners of one end of eight 31-inch cards.

  • Mark a center line of width in the two 40 1/2-inch 2 by 4s. Mark a center line at the top and bottom of the posts. Use a straight edge to connect the two marks together along the two stalls.
  • Fit a 31-inch board to two of the posts, aligning the long-side edge, 31-inch with the top edges of the 2-by-4s and the short board edges should align with the center pattern you drew.
  • Mark 13 inches from the bottom edge of the board along the 2 by 4. Connect a second 31-inch board, aligning the edges of the top end with the 13-inch markings and the ends with the centerlines of 2 4. Secure with 3-inch screws.
  • Place both of the 2 by 4s 32 1/2 inches to the left and right of your mid-section. Each 32 1/2-inch should be spaced 21 inches from the workshop 2 by 4s.
  • Place one of the 31-inch angled joints on the left side, above the 2-by-4s short and high. Upper flush edge line with upper left corner of 2 32 1/2 inches by 4; the angled end should be butt against the end of the 31 inches connected to the 2 by 4 high.
