There are a number of upgrades taking place at Melbourne Airport to improve services for passengers.
The airport is investing up to $10 billion over the next 20 years on projects including the expansion of the arrivals area in terminal two and to airline lounges.
Expansion of the arrivals area is scheduled to be completed by the end of the year and will feature new flight information screens, digital media screens and new walkways between baggage claims and customs.
Terminal four, which will be home to Jetstar, Rex and Tigerair, is also taking shape.
The capacity of the ground transport hub and the southern apron and freight area at the airport will also be increased.
The new integrated ground transport hub will provide a central area for pick-ups and drop-offs of passengers by all vehicles, including cars, buses and taxis.
The tri-generation project is approximately 70 per cent complete and is expected to reduce the carbon emissions of the airport by approximately 33 per cent a year.
The aim of the upgrade is to improve access to the airport for passengers and reduce congestion by creating a direct link between Melbourne Airport and the M80 Ring Road and extending Airport Drive.
The project is expected to be finished in the middle of next year.
