This is how a suspension bridge works… | Spark

A medley of knots to make a rope bridge! To make it, you'll need two static ropes that are three times as long as the gaps between your trees, two ropes that are twice the length of the gap (for hand rails), plus sturdy rungs. Carry out all your usual safety checks. It's great for a sense of achievement in the end, and even though we tie the ropes about 1m high on the tree trunk, you always end up quite near the floor. The 'hand rails' are done in the same way but without the rungs and truckers
