Building The Third Runway At Heathrow
This is not concerned about the politics and protests of building the third runway at Heathrow, but about how it could be built and the options for transport to the Airport.

Heathrow Airport With Three Runways
Note.
- How the M25 is dropped into a tunnel.
- The village of Harmondsworth is no more.
- This page on the Heathrow we site gives a lot more details.
Construction
It looks to me, that the actual transformation of the Airport will be possible, as it looks like construction would just replace the housing with the new runway and associated works.
Diversion Of The M25
Cut and cover tunnels would carry the M25 under the new runway, but from the map, it looks like the motorway will only be in tunnel under the new part of the airport and for not that great a distance.
I think with careful planning, the M25 could be left functioning, whilst the tunnel and new runway are constructed, so it should be nothing like the problems of constructing Terminal 5.
Conclusion
The new runway and terminal shouldn’t be the world’s most difficult construction project.
