There is a lot that modern day engineers can learn from the success of the Incas in construction of their road network. First, the Inca road system was constructed in such a way that it led to the expansion of a small kingdom into the largest empire. The lesson is that modern day engineering projects need to focus on a larger picture of city expansions. This is because most project presently focus on decongesting cities instead of expanding them.
Second, a proper understanding of the environment is the key to developing long lasting roads. Instead of constructing road systems and infrastructures that conflict with the environment, modern day engineer should tailor their projects to agree with it. Modern day roads are easily destroyed by water annually. The Incas understanding of water is what guided them in the construction of the long lasting road network. The Incas also considered the seismic events that could have destroyed their roads. This led to the construction of the roads in places that were suitable and dependable. Therefore, modern day engineers need to think of such factors keenly before any major construction are attempted.
