Transport for NSW is planning upgrades to the M1 Princes Motorway between Picton Road and Bulli Tops. The upgrades would improve road safety, travel time and efficiency.
The Australian and New South Wales governments are jointly funding these improvements, with the Australian Government committing $42 million and the NSW Government committing $42.1 million.
APR 2019Detailed design works completed
The detailed design work for stage one improvements on the M1 Princes Motorway between Picton Road and Bulli Tops has been completed.More information
There have been no major changes since the concept design was displayed.
We will continue to keep the community and stakeholders informed as the project progresses.
Timing of construction is yet to be confirmed.
On 1 December 2017 Roads and Maritime Services awarded the design and environmental impact assessment a contract to GHD to complete the detailed design for stage one of the project between Picton Road and Bellambi Creek, and the concept design and environmental impact assessment for stage two of the project between Bellambi Creek and Bulli Tops.
In June 2017, Roads and Maritime published a Submissions Report in response to the display of the environmental assessment for the first stage of the project.
A total of 11 submissions were received in response to the display. This included submissions from five government agencies, Endeavour Energy, one bus company and four from members of the community. Of the submissions received, one was supportive of the proposal, one objected and all other submissions did not offer a position.
The submissions report is available on the project documents page.
The M1 Princes Motorway (M1) between Picton Road and Bulli Tops is currently two lanes in each direction and carries about 39,000 vehicles a day, 13 percent of which are heavy vehicles.
The M1 at this location has challenging topography with sections of the road having steep hills and tight curves making it difficult for heavy vehicles to maintain a constant speed. Due to the steepness of the road and the tight turns, heavy vehicles travel slowly which can lead to a large difference in speeds between light and heavy vehicles.
The project would widen and realign the road and add a new lane in each direction to create a six lane divided road between Picton Road and Bellambi Creek (stage one) and between Bellambi Creek and Bulli Tops (stage two).
- improved travel time and traffic efficiency with the inclusion of an additional lane in each direction
- improved road safety through separation of slower moving and faster moving vehicles
- provide for safer access to carry out maintenance tasks and to utility services
- increased reliability of access into and out of the Illawarra region and Port Kembla including for general freight, larger restricted access vehicles and high performance freight vehicles.
