10 Longest Road Tunnels of the World

Since the dawn of civilization, people have been building tunnels for accessing tombs or underground quarries, or in the hill slopes for allowing the flow of water from porous rocks. Romans were skilled tunnel builders, who made several kilometers long underground passages using the work of slaves.
