Tunnelling across London for the £14.8 billion Crossrail project has been completed.
You won’t be able to use the service until 2018 but to get a feel for how it’ll be, take a look at the drone footage below.
Slightly nauseating, yes, but you get a real sense of how extensive the project is.
Work began in 2012 and according to a video released by the company, tunnelling took place 24 hours a day, seven days a week. Services will run from Shenfield in Essex to as west as Reading.
The three-year process saw 250,000 concrete tunnel segments used and 400,000 apprenticeships created.
8 giant tunnel boring machines were used to excavate 7-million tonnes of material, of which 98% was recycled.
Prime Minister David Cameron visited Farringdon’s Crossrail site on Wednesday and hailed it as “an engineering triumph”.
