Heathrow expansion plan faces sky high challenges

«The biggest unknown is the project’s pricetag. A third runway at Heathrow would be one of the most expensive private sector infrastructure projects in the UK. The estimated cost was £14bn in 2014, but that number would now be far higher.»

Remarkable, really. That £14bn is almost twice as high as the total costs of the Brenner tunnel (two parallel 55km railway tunnels, €8bn in 2017 money) and this for <1km of motorway reconstruction, buying and demolishing 750 homes and building runways/taxiways. An average of £3m per home is still only £2bn, how do they plan to spend much more than £10bn?
