This is “Godlike” level bushcrafting right here.
It takes place in Peru, in the Apurímac river region. The knowledge and technique used have been passed along from parents to children for hundreds, maybe thousands of years from their Inca ancestors.
The plant used it called “q’oya”, which is particularly strong. The long, strong blades are worked into rope. Each of the four communities brings rope to build the bridge.
It’s a community effort, involving a thousand villagers from all over the region that comes together to make the bridge. Even the children help.
Once a year during the second week of July they get together to cut down the old one and rebuild the bridge again. They also have a party to celebrate the occasion.
