The expansion

Expanding Heathrow Airport is one of the largest infrastructure projects in the UK and the first, new full length runway to be built in the south east of England since World War II.  The proposed expansion will not just be about constructing a new runway to the north west of the existing northern runway. As part of the expansion, Heathrow Airport Limited (HAL) have said there will be the need to provide:

  • terminal, apron and baggage infrastructure to serve the extra aircraft and passengers
  • facilities within the airport boundary to handle cargo imports and exports
  • taxiways to connect the new runway with the existing airport and expanded airport facilities
  • supporting and related facilities for the airport such as aircraft maintenance, fuel storage, car parking and ground support equipment

To achieve the above, HAL have said there is also the need to:

  • re-position and build over part of the M25 motorway and improve the associated junctions to handle the altered traffic flow
  • re-align other local road networks including diversions to the A4 and A3044
  • upgrade the current central bus station
  • develop additional terminal and satellite buildings and changes to internal access roads
  • develop additional aircraft stands and apron spaced
  • divert local rivers such as the River Colne, the Colne Brook, the River Wraysbury, the Longford River and the Duke of Northumberland's River and create new areas (compensatory) of flood storage
  • provide new areas for landscaping, protecting habitats and wildlife corridors
  • provide new space for airport supporting facilities including, but not limited to hotels, offices, consolidated car parks, freight forwarding and flight catering facilities, an air traffic control tower; upgraded and new wastewater treatment and network infrastructure; diversion, relocation, protection and/or expansion of the public utilities network; energy generation plant; upgraded and new waste and recycling centres 
  • replace certain commercial uses, infrastructure and major facilities currently in place at the existing airport such as: Immigration Removal Centres, Lakeside Waste Management Facilities and British Airways' Waterside office
  • use temporary construction areas and facilities, including contractor compounds, lorry parks, concrete plants, assembly facilities, borrow pits, stockpiles and construction workers' accommodation and proposed use of offsite logistics hubs located across the UK for the delivery of materials to build the new runway and expanded airport
