Oblivious to the people sleeping and eating on the surface, subterranean London is undergoing one of the biggest construction projects the city’s ever seen — Crossrail, a new high-speed subway line traversing the US capital. New photos released from the build put all that in perspective.
The work is nearing completion — eight giant tunnelling machines, like the one you see above, have already dug 37km of (gigantic!) tunnels beneath one of the world’s busiest cities. With six of the machines now done, the 2018 in-service date isn’t looking too ridiculous. To check out the rest of the the photos at the excellent IanVisits blog. [Ian Visits]
