M25 tunnel central to Heathrow expansion plans

Heathrow Airport has laid out plans to lower and place the M25 in a tunnel as part of its public consultation launched today to gain approval for its expansion plans.

The 10-week consultation offers the public an opportunity to shape Heathrow’s future and how the airport will serve local communities and the UK.

According to Heathrow, the consultation is a key milestone in the expansion plans and comes ahead of a parliamentary vote in the first six months on a national policy statement for the new north-west runway.

Heathrow is proposing to realign the M25 to make way for its new runway by repositioning it 150m to the west and lowering it by 7m, as well as raising the runway height over the M25. Heathrow is also proposing junction improvements on the M25.

In addition to realignment of the M25, the consultation includes three options for the new runway and terminal development plans.

Feedback is also being sought on the operational aspects of the expanded airport.

“When the government announced its support for Heathrow expansion it made a clear commitment to keeping Britain open for business,” said Heathrow executive director for expansion Emma Gilthorpe. “We want an expanded Heathrow to be the world’s best airport, ensuring that our country and its future generations have the infrastructure they need to thrive.

“We need feedback to help deliver this opportunity responsibly and to create a long-term legacy both at a local and national level. Heathrow is consulting to ensure that we deliver benefits for our passengers, businesses across the country but also, importantly, for those neighbours closest to us.”
