Work Under Way on Sydney’s $720m Richmond Road Project

A $720-million upgrade to one of Western Sydney’s busiest roads has broken ground.

The project aims to improve access around growing residential, data centre, and industrial districts at Marsden Park, about 40km north-west of the Sydney CBD.

The Richmond Road works, consisting of three related projects, are projected to cut morning peak travel times by up to 21 per cent and afternoon peaks by up to 34 per cent.

As many as 89,000 vehicles currently use Richmond Road every day, with movements projected to increase significantly in the near future. Deputy premier Prue Car said the project would “deliver much-needed relief on one of the most congested roads in Sydney”.

About 2.2km of Richmond Road between the M7 Motorway and Townson Road will be expanded from four to six lanes, at a cost of $520 million. A new flyover bridge will bypass two sets of traffic lights when exiting the Motorway northbound. Separately, funding to upgrade Townson Road was also announced in January 2025. 

Another $150 million of the Richmond Road package will be devoted to widening from two lanes to four lanes between Elara Boulevard and Heritage Road, with a central median to potentially accommodate two more lanes in the future.

A Richmond Road Corridor planning project has also been allocated $50 million, investigating investment opportunities along Richmond Road. 

Bus infrastructure, flood works and a shared path into Marsden Park are also included in the overall package of works.

Funding for the road upgrade two projects has been contributed in equal proportions by the NSW and Federal governments, while the planning project has received $37 million from the Commonwealth.

▲ Richmond Road currently has 89,000 vehicle movements per day, and traffic will increase as residential density grows and data centres are built.

In total, the Federal Government has an $18–billion infrastructure pipeline in Western Sydney, while the NSW government has committed $7.4 billion to Western Sydney roads since March 2023.

In January 2026, Kanebridge requested SEARs for a $500-million, 1320-home new precinct at 264a South Street in Marsden Park. At the time, development manager Ronnie Rahme told The Urban Developer that, with a potential future Metro station on the way, Kanebridge “see[s] it as an exciting opportunity for a placemaking project”.

Another 23,000 residents are expected in the area by 2036, according to a study by Atlas Economics, and state government-led rezoning to accommodate a further 4000 homes is under way.

Data centres sprouting near Richmond Road

CDC is currently progressing a $3.1-billion, 504MW data centre campus at 105 and 113 Hollinsworth Road, which would become the largest in the southern hemisphere. 

▲ Data centres are rising to the north and south of the Light Horse Interchange where the M4 and M7 motorways meet.

The site is among the existing Marsden Park Industrial Precinct just off the intersection of Richmond Road and the M7 Motorway. Industrial and logistics facilities in the precinct include those operated by DHL, Maersk, and the NSW Rural Fire Service. Big box retailers including IKEA, CostCo and Bunnings also hold assets in the vicinity.

About 10km to the south, another data centre hub is emerging at Eastern Creek. Goodman requested SEARs in January for the $5-billion, 550MVA Project Atlas at 10 Roberts Road, replacing the cold-chain logistics facility currently on the site.

Another CDC data centre at 17 Roberts Road, completed in 2022, is currently the largest in the southern hemisphere, with 200MW capacity and a price tag of $1.5 billion.

And NextDC announced plans to develop a 550MW data centre at its Eastern Creek S7 site in December 2025. If delivered at that scale, the project would then claim the title of the southern hemisphere’s largest data centre.

However, contenders for the title continue to crop up. Earlier this month, Singaporean asset manager Keppel announced a land access deal for a $10-billion, 720MW project near Morwell in Victoria.
