Quick Summary

Heathrow Airport has proposed rerouting part of the M25 to accommodate a third runway, aiming to minimize disruption by building a new section 130 meters west of the existing motorway and transferring traffic through planned overnight closures. The project is estimated to cost £49 billion, with Heathrow claiming it will create over 100,000 jobs and attract £33 billion in private investment. Critics argue that economic benefits are overstated, and the plan faces skepticism due to past M25 construction disruptions.

Story summary

Heathrow Airport's plan for a third runway includes rerouting part of the M25, one of Britain’s busiest motorways. The airport proposes building a new section of the M25 130 meters west of its current location, which would allow most construction work to occur without disrupting traffic flow. This proposal aims to address concerns about lengthy disruptions and delays that occurred during previous highway improvements near Junction 10 in Surrey.

Under Sir Keir Starmer’s administration, supported by Chancellor Rachel Reeves, the government has backed the expansion project as a means of boosting economic growth despite imposing business taxes. The third runway is estimated to cost around £49 billion and faces potential years of delays. Heathrow now hopes this rerouting strategy will gain wider support among Londoners and secure further government backing for the ambitious infrastructure development.

Critics remain skeptical, citing past disruptions and questioning whether such a complex plan can avoid significant traffic issues during construction.
