The ancient civilization that built extensive road systems to connect their empire is the Romans. The Roman road network was essential for military, commercial, and administrative purposes, enabling efficient movement across the vast territories of the Roman Empire. Spanning over 250,000 miles at its height, these roads were engineered for durability and directness, often featuring layered construction to withstand traffic and weather. The phrase "All roads lead to Rome" highlights their significance in unifying the empire, facilitating trade, cultural exchange, and military logistics, and leaving a lasting impact on infrastructure development in the Western world.
