Tunnels are underground passages used for transportation purposes. Rather than attempting to go around or over a geographical barrier, they burrow through or under the barrier. They can be used as an extension of normal passenger roadways or for rail or even water transport. Use Wolfram|Alpha to explore a multitude of tunnels worldwide, including many of their properties.
