Travellers are being warned there will be fewer places to park at Melbourne Airport, including over the busy Labour Day long weekend and Easter holiday period.

Construction will begin in March on the second stage of a new elevated road, known as Naarm Way, connecting the Tullamarine Freeway to new passenger pick-up and drop-off zones inside the airport's multi-storey car park.

Qantas, Virgin and international passenger zones will be moved to levels two and three of the T123 carpark, requiring the closure of 2,000 parking spaces.

Melbourne Airport's chief of Ground Transport, Property & Retail, Jai McDermott, said the project will make it easier to enter and exit the airport once it is completed.

"It'll mean a quicker, more reliable and less stressful journey time for people coming to and from the airport by car," Mr McDermott said.

Five hundred of the car parking bay losses will be temporary during construction, but 1,500 will be permanent.

Mr McDermott said it represented just 10 per cent of Melbourne Airport's 24,000 car parking bays.

He admitted it could be tricky to find a park during peak travel times, such as long weekends and Easter.

But he said the airport had planned for those periods and urged travellers to book ahead to guarantee a spot.

Mr McDermott said air travel had returned to pre-pandemic levels, and moving the passenger drop-off zone to inside the multi-level car park would help avoid queues of cars leading into the airport.

"It's about investing ahead of those congestion issues arising so we're ready for the growth that's going to come over the next 10 to 20 years," he said.

Once the new road was completed in 2026, only Skybus, taxi and ride share passengers will use the existing drop-off zones in between the terminals and multi-storey car park.

The $70 million first stage of the project involved a new exit from the Tullamarine Freeway to Terminal 4, which eliminated multiple intersections between the freeway and airport terminals.

The Corporation said Naarm Way was Melbourne Airport's largest road investment since Airport Drive opened in 2015.
