What is cost of roman road?

The cost of constructing a Roman road varied significantly based on factors such as location, materials, labor, and the specific engineering techniques employed. Historical estimates suggest that building a mile of Roman road could range from a few thousand to tens of thousands of denarii, depending on these variables. Additionally, the long-term economic benefits of enhanced trade and movement often outweighed the initial investment. Ultimately, the cost was justified by the roads' crucial role in expanding the Roman Empire and facilitating communication and commerce.
