So when the Incas needed to travel across the Andes, they did so on handwoven rope bridges, stretched over gorges and rivers. Five hundred years later, just one of the Inca rope bridges remains: the Keshwa Chaca, which spans the Apurimac River near Huinchiri, Peru, in the Province of Canas. Dangerous work: Local villagers work on renewing the Keshwa Chaca - the last Inca rope bridge - in the Andes near Huinchiri, Peru Incredible skill: The 90ft long Keshwa Chaca remains thanks to local villagers who rebuild the bridge each year using the same techniques as their Inca ancestorsInca kingdom in the Andes was connected via handwoven rope bridgesToday, only one bridge remains - the Keshwa Chaca near Huinchiri, PeruThe 90ft-long bridge is rebuilt by villagers over three days every June, before gradually disintegrating each timeLocals use the same techniques to make the rope as their Inca ancestors
