Build an Elevated Platform Walkway for Sloped or Wet Terrain

This affordable solution is built like a simple deck: 4x4 posts in postholes support a 2x6 frame with 2x6 decking. Platforms can step down a steep slope or incline 1 ft in 12 ft for comfortable descent. Pressure-treated lumber is essential for ground contact. Plan 36-in. width with footings every 8 ft.

What You Need

• 4x4 posts
• 2x6 joists
• 2x6 decking
• 3-in. galvanized deck screws
• ¼x6-in. hex-headed bolts, nuts, washers
• Gravel
• Weed barrier: PVC sheeting or weed-block fabric
• Posthole digger, shovel, rake
• Mason's line and stakes
• Basic carpentry tools

Instructions

1. Install frames and posts. Build 2x6 frames. Use them as guides to dig all postholes. Install posts along one side first: 3 in. gravel in each hole, set and plumb posts, pack gravel around. Fasten one frame side to each post with lag bolts, leveling as you go. Use frame to guide opposite row of posts, fasten them. Trim 4x4 tops flush with frame.

2. Add planks. Lay weed barrier and pea gravel to suppress growth underneath. Cut 2x6s to 36 in., fasten to joists with 3-in. deck screws, maintaining ¼-in. gap between treads. Square up occasionally with framing square.
