A day in their shoes..

Fascinating. This article has 2 stories in 1: the tunnel being built under the Bosphorous and the ancient civilization uncovered.
The history part, while pretty wow, is not what amazed me. Its the building of the tunnel that did. Its such a massive and dangerous undertaking that they actually have an emergency bunker on the bottom of the sea that is stocked with emergency supplies up to 10 days in case of a flood. Imagine walking a day in the shoes of one of the tunnel construction workers. Fascinating.
Tunnel links continents, uncovers ancient history
