Heathrow Expansion and the M25 Debate
British Airways' chief executive, Sean Doyle, supports expanding Heathrow Airport without relocating the M25 motorway if feasible. He acknowledged the logic of building a third runway without diverting the major road.
Government Proposals for Expansion
The government is reviewing two key proposals to expand Heathrow:
- Heathrow Airport Holdings Limited's plan: This involves rerouting the M25 motorway between Junctions 14 and 15 through an underground tunnel, allowing the construction of a full-length 3,500-metre runway.
- Arora Group's plan: Proposes a shorter 2,800-metre runway, which eliminates the need to move the motorway.
Views from Industry Leaders
At the Airlines 2025 conference in Westminster, Sean Doyle stated:
“If you can avoid moving the M25, you should avoid moving the M25. I can’t argue against the logic of that. I think we should look at ways of potentially building a shorter runway.”
On the other hand, Heathrow’s chief executive Thomas Woldbye insisted that relocating the M25 is essential to construct a third runway that significantly increases capacity. He emphasized that a shorter runway:
“Would cost almost the same but deliver much less capacity. It just does not make sense.”
Summary
The debate centers on balancing infrastructure impact with airport capacity, weighing the benefits of a longer runway against the disruption of moving the M25.
