9. Assist in the construction of a ten-foot (3.0 meters) long log or rope bridge, using lashings.
Log Bridge
The simplest way to make this bridge is with poles. Cut two long poles at least 15 cm in diameter and long enough to span the item to be bridged. Then cut several smaller poles at least 5cm in diameter and approximately 60 cm long. Place the long poles over the gap to be spanned such that the short poles can lay across them, overhanging by 3-5cm on both sides. Then use continuous lashing to attach the short poles to the long ones. A rope hand rail can be added for additional balance.
