Built in Britain S01E01 - Episode 1

Evan Davis gains access to bits of Britain you never see, to look at the scale of the engineering challenge Britain faces, and how we can tackle it. He visits the vast Crossrail boring machines burrowing their way under London's streets, takes in the breathtaking views at top of the Forth Road Bridge, and sees the teeming runways of Heathrow Airport from the tarmac.
