Built to Last: The Secret that Enabled Roman Roads to Withstand the Passage of Time

The Romans were renowned as great engineers and this is evident in the many structures that they left behind. One particular type of construction that the Romans were famous for is their roads. It was these roads, which the Romans called viae, that enabled them to build and maintain their empire. How did they create this infrastructure that has withstood the passing of time better than most its modern counterparts?

Roads of All Kinds

It has been calculated that the network of Roman roads covered a distance of over 400,000 km (248,548.47 miles), with more than 120,000 km (74,564.54 miles) of this being of the type known as ‘public roads’. Spreading across the Romans’ vast empire from Great Britain in the north to Morocco in the south, and from Portugal in the west to Iraq in the East, they allowed people and goods to travel quickly from one part of the empire to another.
