The Q'eswachaka Bridge, one of the last remaining bridges once common in the Inca road system, spans the Apurimac River in the province of Canas about 160km south of Cusco. It is rebuilt every year by villagers from either side of the canyon in a three day. two-community marathon employing an ancient Incan engineering technique handed down for hundreds of years. Everyone takes part in weaving the ropes of twisted grass and braiding them into cables, then all join to pull them as taut as possible. Two master weavers work from either side of the bridge until they meet in the middle. Rejoice with the communities as they celebrate the completion of this year's bridge.
