Interesting article. I was surprised by how mature and automated the technology was, given how relatively few tunnelling operations of this scale have been attempted.
Also, the concrete slabs, and presumably therefore the tunnel, have a projected lifespan of 120 years [1]. I wonder what use the tunnels will be put to in 2120?
