Detailed explanation-1: -To facilitate trade across the Empire, a huge and complex road network spanning over 35, 000 km., the Qhapac Ñan, was built, which included hanging bridges over rivers and rest stops, or tambos.
Detailed explanation-2: -The Incas developed techniques to overcome the difficult territory of the Andes: on steep slopes they built stone steps, while in desert areas near the coast they built low walls to keep the sand from drifting over the road.
Detailed explanation-3: -Flattened road beds-often raised-were usually made using packed earth, sand, or grass. The more important roads were finished with precisely arranged paving stones or cobbles. Roads were typically edged and protected with small stone walls, stone markers, wooden or cane posts, or piles of stones.
Detailed explanation-4: -The Incas built causeways to elevate the roads in swampy areas. They also built amazing bridges, which they called chacas. The hanging bridges are the most famous of the Incan chacas. One Incan bridge was over 250 feet long.
