The Indira Gandhi International (IGI) Airport in Delhi, India, is set to execute a major expansion project to increase passenger handling capacity.

The expansion project covers a new terminal, advanced facilities, an additional runway and improved capacity to handle more passengers.

Hindustan Times reported that IGI will become the country’s first airport to feature four runways after its completion.

Scheduled for construction next year, the fourth runway will raise the hourly flight handling capacity of the airport and reduce the waiting time for arriving and departing flights.

In addition, IGI’s annual passenger traffic handling capacity will increase from 20 million to 40 million passengers.

According to a Live Hindustan report, the new terminal (T4) is expected to be completed by 2025 and will help in the reduction of airport traffic as it will only serve international travellers.

New taxiways will also be included, which will be connected with the existing T1 and T3 terminals.

The airport will also feature a unique ‘dual elevated cross taxiway’, which will cut down the aircraft’s taxiing time.

The total T1 area will be expanded and additional lanes will be added to the terminal’s departure ramp to improve traffic circulation.

In addition, a corridor for cargo movement in and out of the airport will be created for separating heavy vehicle movement from passenger vehicles.

A seventh check-in island will also be added in T3 and the international transfer area will be expanded.

On another note, the Government of India (GoI) has announced plans to develop 100 additional airports in tier two and three towns and cities across the country in an attempt to enhance air connectivity.
