The roads were built for safety and comfort...
The roads were built a few feet off the ground. This is because they put ditches and canals on both sides. This prevented flooding during the rainy seasons. The water would run off the roads into the ditches.
The roads increased trade greatly. They allowed traders to move easily from city to city within the empire. Traders could also move goods from the center of the country to important water ways and rivers. There goods could then be shipped and sold to other countries.
