Monkey Bridge (The Real Deal)

The well-known, time-tested, traditional Monkey Bridge is perhaps the most familiar of all Scout pioneering projects. It’s frequently featured at Scout Expos, Camporees, Scout Camps, and is often a central attraction at public gatherings where Scouting is represented.

Using a double A-frame to build a monkey bridge is a departure from the usual X-frame that supports the foot rope and hand ropes. This new method has two distinct advantages over the X- frame version.

First, the double A-frame provides a wider base making it less likely to tip over. The second advantage is that the positions of the A-frames can be adjusted so the span between the hand ropes can be narrowed for better balance as you make the crossing.

Here's a detailed, step by step procedure and list of materials.

One major step that was not included in this instructable is ANCHORING! Of course, each side of the bridge has to be anchored, and this is explained in the detailed procedure, along with diagrams and descriptions of knots and lashings used during the building process.
