Albion Park Rail bypass - Princes Highway upgrade

Transport for NSW is building an extension of the M1 Princes Motorway between Yallah and Oak Flats to bypass Albion Park Rail. The NSW Government is funding the $630 million project. The bypass would complete the 'missing link' for a high standard road between Sydney and Bomaderry. Motorists are expected to be driving on the new motorway by mid-2021, with the project on track for completion in late 2021.

There will be changes to the northbound access to Dapto from Monday 22 February, weather permitting.

To progress work on the new motorway and ramps in Yallah, we are moving the northbound access to Dapto further south. Motorists heading north wishing to exit to Dapto will need to follow new signage for the exit ramp.

Further traffic changes will occur across the project later this year, as parts of the new motorway progressively open to traffic. We will keep the community and motorists informed as we progress.

Please see the video of these changes.

NOV 2020Project tracking ahead of schedule

Construction of the Albion Park Rail bypass is more than a year ahead of schedule with motorists now expected to be driving on the new Princes Motorway from mid-2021, weather permitting.

More than 2 million hours have been worked on the project, and a number of significant milestones have passed since major work began in January last year.

There will be several traffic changes over the coming months including on the East West Link Road, Oak Flat Interchange and onto the new motorway.

Once traffic has been moved onto the motorway, work to complete the project will continue into late 2021 including finishing earthworks, bridge construction, shared paths and pavement work.

The community will be kept informed as the project progresses. Thank you for your patience during the construction of the bypass.

APR 2020Work hours extended to support industry during COVID-19

The NSW Government has announced construction sites can now operate on weekends and public holidays to support the industry during the COVID-19 pandemic.

The extended hours allow the industry to facilitate social distancing on construction sites, while minimising the potential for lost productivity.

During this time, construction work may be carried out Monday to Sunday 7am to 7pm and on public holidays.

The local community will be informed in advance if work is required outside of these hours.

We will continue to make every effort to minimise construction impacts where possible. 

Should these circumstances change, we will advise the community and will return to our standard construction hours of Monday to Friday 7am to 7pm and Saturdays 8am to 5pm.

We appreciate this is a difficult time for many and would like to remind the community that we can be contacted by phone 1800 708 727 (toll free) and email
