Tunnel - List of longest tunnels - Netflix

This list of longest tunnels in the world ranks tunnels that are at least 13 km (43,000 ft) long. Only continuous tunnels are included; pipelines (also buried) are excluded. The longest have been constructed for water distribution, followed by tunnels for railways. Both uses are highly sensitive to gradients.
