M1 Princes Motorway projects

Reviewed

The M1 Princes Motorway carries significant commuter, heavy vehicle and recreational traffic. Transport for NSW is planning a number of projects to increase network capacity, cater for future traffic demands and improve safety for road users.

Transport is also investigating broader transport solutions to improve multi-modal connectivity between Shellharbour and Wollongong.  These solutions will address anticipated changes across the Illawarra including the West Lake Illawarra Growth Area. 

This work will build on the preliminary investigations carried out as part of the earlier ‘Improvements between Figtree and Dapto’ project which focused on improving safety and efficiency for private vehicles along the motorway. 

The multi-modal transport investigations consider options to improve the efficiency of the motorway, including: 

  • infrastructure improvements
  • new public transport services
  • options outside of the immediate motorway corridor to improve the travel experience of road users across different travel modes.

Transport is committed to consulting the community throughout all stages of the planning process. We will keep the community informed as each project progresses.

Project information

Mount Ousley interchange

Transport has started planning for an interchange on the M1 at the base of Mount Ousley.

The interchange will look at future traffic growth and improve road safety at this location.

Please visit the Mount Ousley interchange project page or call the project team on 1800 792 918 or email mountousleyinterchange@transport.nsw.gov.au.

Improvements between Picton Road and Bulli Tops

The M1 Princes Motorway between Picton Road and Bulli Tops is currently two lanes in each direction.

This section of road carries about 37,000 vehicles a day, 15 per cent of which are heavy vehicles. Traffic numbers will continue to increase along this route.

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 provide additional lanes and improve the curves. This would increase the safety, capacity and efficiency of the M1 Princes Motorway.

Please visit the Picton Road to Bulli Tops project page or call the project team on 1800 727 714 or email PictonRoadtoBulliTops@transport.nsw.gov.au.

South facing ramps at Dapto

Transport has started planning for additional entry and exit ramps to connect motorists in Dapto to the M1 Princes Motorway.

The new south facing ramps aim to reduce the distance and time residents of Dapto and neighbouring suburbs must travel to head south.

Please visit the south facing ramps at Dapto project page or email southprojects@transport.nsw.gov.au.
