A4: Heathrow Airport

Question: To ask the Secretary of State for Transport where she plans the A4 to run in relation to Heathrow airport in proposals in the Adding Capacity at Heathrow consultation; and what assessment she has made of the security implications of the location of the road.

Answer: It is expected that the routing of the A4 would be largely unaffected by the proposals in the 'Adding Capacity at Heathrow Airport' consultation document. It is, however, expected that sections of the road would pass in tunnels underneath aeroplane taxiways between the existing airport campus and the new runway. If proposals are taken forward, further work would need to be carried out as part of a comprehensive transport assessment prior to the airport operator submitting any planning application: this would include any security implications of the location of the A4. This would be done in consultation with the Highways Agency, TfL and local authorities.
