Question: Which ancient civilization is credited with building the first extensive paved road network?

Answer: C. Romans

When asked which ancient civilization is credited with building the first extensive paved road network, the answer is unequivocally the Roman Empire.

Known for their engineering ingenuity and administrative ambition, the Romans created a vast, durable and strategically vital network of roads that connected their sprawling empire and influenced infrastructure development for centuries to come.

The Romans began constructing roads in the 4th century BCE, starting with the Via Appia (Appian Way) in 312 BCE, which connected Rome to Capua and later extended to Brindisi. This road, one of the earliest and most strategically important, set the standard for future Roman roads.

These roads were built with a sophisticated multi-layer technique. A typical Roman road had a deep foundation of compacted earth, followed by layers of gravel, crushed stone and large paving stones on top, according to an article from the American Society of Civil Engineers (ASCE). This design allowed for efficient drainage and longevity.

Beyond transportation, Roman roads served crucial military and administrative functions. They allowed legions to move quickly across territories, helping to maintain control over far-flung provinces.

The road system also supported communication and commerce, unifying the empire economically and culturally.

The Roman road system was unparalleled in the ancient world in both scale and design. Roads like the Via Egnatia or Via Augusta enabled trade, troop movement and cultural exchange across three continents.

Roman engineers prioritized straight lines and durable materials, often cutting through mountains and building bridges or tunnels to maintain their routes. Roads were slightly arched (cambered) to shed rainwater, reducing erosion and damage. Many of their construction practices remain in use today, according to ASCE.

The design of Roman roads was so effective that many routes remain the foundation of modern roads in Europe. Roads were marked with milestones and maintained regularly by the state or contracted entities.

At the height of the Roman Empire, the road system extended over 250,000 miles, with more than 50,000 miles paved. A well-documented itinerary system helped travelers navigate the network efficiently.

The famous saying, “All roads lead to Rome,” reflects this central design. The empire's commitment to maintaining this network helped facilitate trade, government control and cultural cohesion across a vast and diverse region.

Even after the fall of the Western Roman Empire, the roads continued to serve European societies for centuries, often forming the backbone of medieval and modern roadways.

The Roman Empire’s pioneering efforts in road construction remain one of the most enduring legacies of ancient engineering. Their commitment to connectivity, durability and strategic planning helped shape the ancient world and laid the foundation for modern infrastructure.

So, when it comes to the civilization that built the first extensive paved road network, history gives full credit to the Romans.
