Step-by-step explanation:
The construction of an extensive network of roads by the Roman Empire had a major long-term effect of accelerated trade and communication.
The Romans built over 40,000 miles of roads that connected various cities and regions, allowing for efficient transportation of goods and people. This network of roads facilitated trade and communication between different parts of the empire, leading to increased economic activity and cultural exchange.
For example, the Roman road system enabled the transportation of goods such as grain, olive oil, and wine across long distances, boosting trade and contributing to the prosperity of the empire. It also allowed for the movement of troops and government officials, ensuring better administration and control of the empire.
