One of the most fascinating bridges featured in the World’s Most Extreme Bridges is the Living Root Bridge. These bridges are constructed by training the roots of certain species of trees to grow into a natural bridge over a body of water. The process can take several years, but the resulting bridges are strong, durable, and beautiful. The documentary provides a detailed explanation of how the bridges are constructed and the cultural significance of the bridge in the communities where they are found.
