This Bridge is Rebuilt by Hand Every Year

The Q'eswachaka Bridge spans the Apurimac River Canyon in Peru, and links two communities. Every year, the communities come together to replace last year’s rope bridge with a new one made of strong, new grass. They’ve done this for hundreds of years, from the time of the Inka, with the process handed down through generations. Watch how they do it. Noonday Films made this video for the National Museum of the American Indian in Washington, D.C., specifically for the exhibit “The Great Inka Road: Engineering an Empire.” The exhibit opened in June and will be on display until June of 2018.
