The correct answer is to this question is D) Roman roads were built only in times of peace.

The statement that is true of the Roman Road system is "Roman roads were built only in times of peace."

In those years of the Roman Empire, the Roman army needed good roads for the transportation of soldiers, weapons, supplies, and goods. Roman engineers used the technique called "Goma" to build roads in stretched places. They dug ditches on both sides of the road that served as drains. The collected rock from the area and put them in layers until they were heavy enough for the heavy Roman carts. The thing with the Roman roads is that the roads were only built in times of peace.
