Build a footbridge
This is a 40-foot long footbridge over a wetland and brook. There are four “decks”; each deck section is 10’ long x 4’ wide. This foot bridge uses Sunwalk Perforated Decking to allow sunlight and rain through to allow vegetation to grow underneath.
Each 4’ x 10’ section is constructed with 2x6” pressure treated lumber and is mounted on 4x4” pressure treated posts. The sections are connected by two J-Brackets on each end. Each post is mounted using an aluminum Post Bracket. This allows for easy adjustment of the deck for leveling or future replacement of posts.

Post Bracket and Brace clamps

The posts are sharpened (see video tip on sharpening posts quickly and easily), then driven into the ground with a Post Driving Cap. If a post cannot be driven into the ground, then a Post Foot can be used instead to stabilize the post in place.
