At the height of Rome's power they had more than 29 great military highways, 113 provinces were interconnected by 372 great road-links, and the whole road system comprised more than 400,000 km of roads, of which over 80,500 km were stone-paved. This enabled the romans to flourish as a civilization for over 400 years and to project their power and influence to the ends of the known world.
The Roman roads offered value in many ways. They enabled trade and supplies to move, cultural influences to expand, knowledge to be shared and the use of effective military strategies based on the predictable movements of Roman legionnaires who could march 24 miles in 5 summer hours when pressed for short amounts of time, and 20 miles a day indefinitely in all weather. This was only possible because of the investment in and the quality of the roads.
Today the internet is the modern equivalent of the Roman road. Products can be sold, tracked and delivered just about anywhere in the world because of the internet. The internet, however, also enables those with nefarious intent to project power and influence on people around the world, and it is the place where information warfare is now fought.
