Inca Bridge thermal baths (coordinates 13° 31' 46.01" S, 72° 38' 35.02" W), disappeared by the end of the 19th century after 300 years of service. There are still remnants of the access tunnels and the bridge supports. Local organizations are planning to rebuild the bridge with its access roads and tunnels to serve the hiking community and provide a view of the gorge. Inca Bridge The Inca Bridge or Inka Bridge refers to one of two places related to access to Machu Picchu, in Peru. One of the two was built by the Incas as a secret entrance to Machu Picchu
Machu Picchu more farmland to grow crops, and to steepen the slopes that invaders would have to ascend. The terraces reduced soil erosion and protected against landslides. Two high-altitude routes from Machu Picchu cross the mountains back to Cusco, one through the Sun Gate, and the other across the Inca bridge. Both could be blocked easily, should invaders approach along them. The site is roughly divided into an urban sector and an agricultural sector, and into an upper town and a lower town. The temples are in the upper town, the warehouses in the lower. The architecture is adapted to the mountains.
