London Heathrow Airport has submitted its proposals for a brand-new terminal ‘T5X’, the expansion of Terminal 2 and three new satellite terminals – as well as a 100% privately financed third runway.
The £49bn investment consists of three main elements: £21bn (US$27bn) for the new runway and airfield infrastructure (up from £14bn in 2018 due to construction inflation); £12bn (US$16bn) for new terminal and stand capacity – the brand new T5X; and £15bn (US$20bn) to modernize the current airport by expanding Terminal 2 and ultimately closing Terminal 3. The blueprint details a north-western runway up to 3,500m, and increased capacity to accommodate up to 756,000 flights and 150m passengers.
According to the airport, a third runway and supporting infrastructure could be ready within a decade, with the full investment across all terminals taking place over the coming decades...
