Heathrow expansion

Background

The previous government agreed for Heathrow Airport Limited (HAL) to put forward an application for a third runway at Heathrow Airport following a review of options by Sir Howard Davies. This option was chosen over:

  • extending the existing Heathrow Northern Runway
  • a new full length second runway at Gatwick Airport

HAL’s proposal was for a new runway, north-west of the current airport. This new runway would go over and bridge the M25, south of the M4, and run parallel to the Buckinghamshire county border. The proposal would require new terminal capacity to increase passenger numbers from around 80 million per year to 130 million passengers per year by 2035.
