LONDON — Heathrow Airport has unveiled a proposal to expand its airport, including plans to open a new runway by 2026.

This would be the London airport's third runway. The new runway will be 3,500 meters long and would be located in the north-west area of the airport.

By 2050, the airport also plans to unveil a new terminal that would integrate indoor and outdoor spaces. Additional plans include creating a low carbon-emissions zone and reducing noise pollution in the area.
