Roman roads are roads that the Romans build to make sure that messages and people could move easily round the Empire. The roads were helpful for armies, officials, civilians, messengers, and traders. All the roads put together were more than 40,000 kilometres (25,000 miles) long, and 8,500 kilometres (5,300 mi) of the roads are made of stone.
