Recently, the British Foster Architects announced that they are planning the King Salman International Airport in Riyadh, the capital of Saudi Arabia, which will have six runways. This international airport project in the Saudi capital was announced by Crown Prince and Prime Minister Mohammed bin Salman in August 2023 as a national infrastructure development plan, covering an area of 57 square kilometers. In addition to six parallel runways, the plan includes the construction of residential areas, entertainment facilities, and logistics areas, aiming to create one of the world's largest airports.
The expansion project of King Salman International Airport is based on the existing King Khalid International Airport and is expected to have at least six parallel runways after completion. This expansion project is expected to significantly enhance Saudi Arabia's air transport capacity, with the annual passenger volume expected to increase from the current 29 million to 120 million by 2030, and further to 185 million by 2050. At the same time, the number of aircraft takeoffs and landings in Saudi Arabia will increase from 211,000 per year to over 1 million. If the project can be completed as planned by 2030, it is expected to become the airport with the highest passenger volume in the world.
