Bridges

=Bridges= =by Sandy=

Incan builders built rope bridges for people to walk on. The Incas were master builders. They made bridges over mountains and strong rivers. Bridges were made out of twisted or braided ropes. The cables of the bridge were anchored on each side by stone pillars and weights. Incans were excellent engineers. Without these bridges the entire Incan road system would have been incomplete. Incans built bridges for people to travel from place to place.
