IMBA Resources: Trail Building and Maintenance: 10 Tips to Build a Ladder Bridge


IMBA Resources: Trail Building and Maintenance: 10 Tips to Build a Ladder Bridge: "10 Tips to Build a Ladder Bridge

Originally designed to span wet areas, a ladder bridge is a simple elevated boardwalk and one of the easiest wooden trail features to build. Here are 10 tips for making them fun, durable, and safe.

1. Follow IMBA's Freeriding Guidelines
These tips, in the freeriding section of IMBA's website, provide important information on risk management, design, materials and construction techniques for wooden structures. Before starting, make sure to get permission from the local land manager.

2. Locate the ladder bridge properly
Ladder bridges can be added to trails of various difficulty level - just be sure that the challenge matches the skill of the expected riders. On beginner trails, ladder bridges should be wide and low to the ground. As skill levels increase, the structures can be higher, narrower and incorporate turns, camber changes and drop-offs.

On beginner trails, place the ladder bridge to the side for an optional, more challenging route. On advanced trails, the feature may be located in the main line. However, a clearly visible option around the ladder bridge should always be incorporated into the design."
