London Heathrow's £49 Billion 3rd Runway Delayed By 4 Years, Won't Open Until 2039

The third runway at London Heathrow Airport has been pushed back by four years, now slated for completion in 2039. This significant delay impacts ambitious plans to accommodate 240,000 additional annual flights through the expanded facility. The project’s total cost is estimated at £49 billion, representing a substantial investment in Britain's aviation infrastructure. A key component of the redevelopment involves a complete terminal redesign aimed at improving passenger flow. Furthermore, the construction necessitates a major rerouting of the M25 motorway around the airport site.
