Highways and Roads
In the Roman Empire, highways were critical for trade. The systematic development of roadways by trained engineers allowed for the flourishing of trade and culture. After the second century, the Romans constructed a large road network.
During the first Roman Empire, 30 military routes flowed out of the capital city, with nearly 400 roads connecting them. The highways facilitated speedier communication and commercial commodities exchange. The Roman legions could now travel around 35 to 40 kilometers per day, which was far faster than before.
Roads were not the only thing built. Along the road, the Romans built homes that allowed the army to create communication networks and communicate intelligence and secret information over large distances.
