Step 1
Determine the location of your bridge. The base of the bridge should be on a solid, dry surface. Measure the space and buy materials.
Step 2
Place one pair of concrete pier blocks at each end of the bridge site. Dig out or build up to ensure that the blocks are flush with each other.
Step 3
Connect the beams to the pier blocks. Place the berth on one length of the beam. Attach beams with metal straps.
Step 4
Optionally, create a railing for each side of the bridge. Measure the height of the pillars carefully to make sure they are. Install the pillars in a phased gap to ensure reliable and reliable protection of the railing.
Step 5
Put the boards across the beams to form the steps of the bridge. Cut the boards to a length that allows them to fully rely on each beam, but not too far along the sides of the bridge.
Step 6
Attach the railing to the railing. Measure the correct height and mark each column with a chalk as a visual reference, then firmly attach each section of the manual enclosure.
Step 7
Stain, paint and seal bridge. Use sealant specifically for outdoor use to prevent dampness from destroying wood and destroying your bridge.

1. Use 16 × 2x12 for stringers. Connect both ends of the 2x12 and cut it exactly 16 inches.
2. Measure 4 "at each end of a 2x12 and tick. Find the center of 2x12, measure 1 1/2 (18") left and right and mark. Draw cuts between the labels as shown below.
3. Use a circular saw to cut the stringer along the cutting line. Use the first stringer as a template for marking and cutting other stringers.

1. Cut flooring boards 2x6 to 36 inches for flooring.
2. Center the boards on the frame of the stringer so that about one inch of the overhang is located on each side. Fasten the boards with two screws on each string. Leave a gap of 1/8 "to 1/4" between each board. It may be necessary to cut floorboards to match where the slope bends on the bridge.

For this bridge we decided not to install railways. In most areas, structures up to two feet high should not have a railing, but always check with your local building inspector for requirements in your area. If your local code requires railways or if you want to add them to your bridge.

My wife casually mentioned that a pedestrian bridge over a drainage stream that we created in front and behind would be a nice feature. I decided to surprise her and built bridges in one day. I used 2x12 double-sided lumber for the sides, cut out the arches with a jigsaw, and then transferred this shape to the other side and cut it too.
I left a flat area on the underside at each end where it was resting on the ground. The only limit of design on the cuts is your imagination. If you do not need a high bridge or if it does not cover a wide area, you can use 2x10, 2x8, or even 2x6 lumber. I made my 6 feet long and 24 inches wide, and used 2x4 boards and 2x6 for flooring and 2x6 vertical support in the center to give it greater rigidity.
I used mahogany. If you want to make a smooth arcuate shape, you can use a 1/2 "PVC tube, bend it to the shape you want, screw it to the board, and then follow the curve on the board, it is very durable and looks good. Of course, you can use 2x8 or even 2x6 side boards depending on the range and how you cut the side boards.
