Widening of key road to connect businesses to Western Sydney Airport

Mamre Road is an expanding commercial and logistics corridor linking the M4 Motorway with the new international airport at Badgerys Creek.

The 2024-25 NSW Budget poured $1 billion into road upgrades to open this part of Western Sydney to the world when the airport opens in 2026.

Western Sydney, Australia's fastest growing region, is expected to swell from a population of over two million to more than three million over the next two decades, and the NSW Government is working to provide the roads to accommodate the expansion.

Stage 1 works, which will begin within weeks with clearing and establishment of a site compound, will double the lane capacity of Mamre Road - parts of which remain a single lane in each direction unable to meet the freight and traffic pressure the road is under.

The new four-lane format, with wide central median, will be built to allow a further upgrade to six lanes when needed in future.

The first stage of work on Mamre Road will upgrade a 3.8 kilometre stretch between Erskine Park Road and the M4 motorway at an estimated cost of $290 million.

A wider Mamre Road will reduce congestion experienced by residents and create a new, shared pedestrian-bike path.

Construction company Seymour White will deliver the work, including the construction of two bridge-sized culverts to improve drainage, upgraded intersections to improve safety and travel times, and a new shared path for cyclists and pedestrians.

The NSW Government provided $500 million in the 2024 Budget to progress Stage 2 between Erskine Park Road and Kerrs Road at Kemps Creek. That investment takes total Federal-State funding of Mamre Road to $1 billion.

On Thursday, the first sod will be turned on Access Logistics Park, a 20-hectare industrial development on Mamre Road, Kemps Creek, providing 90,000 square metres of new warehouse and office space and hundreds of jobs in its construction and operations phases. The site is owned by Rest, one of Australia's largest profit-to-member super funds, and investment and development manager Barings.

To the west, work is continuing to transform Mulgoa Road to a four-lane dual carriageway between Glenmore Park and Jeanette Street, improving road capacity to cater for population and employment growth.

Planning is well underway to upgrade Elizabeth Drive, which will take travellers directly to the new airport and connect Mamre and Northen Roads.

Premier Chris Minns said:

"The NSW Labor Government is building better roads and essential infrastructure for Western Sydney.

"We inherited roads around the new airport that were not up to standard, and where upgrades were years behind.

"This area is the engine room for jobs growth and our upgrade of Mamre Road is another boost for Western Sydney's residents and businesses.

"Our recent budget invested a record $5 billion in Western Sydney roads.

"This is all part of the Government's plan to build infrastructure for growing communities."

Minister for Western Sydney Prue Car said:

"It is good to see upgrade works on Mamre Rd will soon begin, and I know the community looks forward to improved traffic flow on this busy road.

"The Liberals and Nationals spent a decade squandering opportunities to upgrade transport links leading to the new Western Sydney Airport.

"We are making the investments needed to open up access to the new airport, which is a key part of Western Sydney's economic future."

Minister for Roads John Graham said:

"The work beginning on Mamre Road is providing construction jobs today, but it is also an investment in jobs of the future as we bring the road infrastructure up to a standard required by the commercial developments going in here.

"This upgrade will see a doubling in lane capacity - turning what is a single-lane, undivided road into a dual-lane carriageway used by about 20,000 motorists each weekday.

"The NSW Government is working hard to make the Sydney motorway system better utilised by truck freight which makes Mamre Road even more important as a critical connector between the M4 Motorway and the future airport.

"While we welcome construction on the first stage today, we also continue the important preparation for the $1 billion Stage 2 upgrade to Mamre Road."

Leppington MP Nathan Hagarty said:

"The NSW Government have committed to upgrading roads in South Western Sydney and this is another step in that process.

"Planning for the future of our community with this upgrade will save on travel times and improve connections to the future Western Sydney Airport.

"After 12 years of inaction and neglect in this part of Sydney, the Minns Labor Government is getting on with job and delivering more reliable and safer roads."

Rest Chief Executive Officer Vicki Doyle said:

"The Access Logistics Park, located on Mamre Road, gives Rest's 2 million members exposure to a world-class industrial facility at the heart of Australia's next global freight and logistics hub.

"This future-focused industrial estate, as well as the upgrades to Mamre Road, will help fuel the economic development of South Western Sydney, a region where tens of thousands of Rest members live and work."
