Mount Ousley interchange

Roads and Maritime Services is planning for an interchange on the M1 Princes Motorway at the base of Mount Ousley. The NSW Government has allocated around $2.5 million to prepare a concept design that would improve road safety, travel times and cater for the efficient movement of future traffic and freight growth.

Updates and announcements

Roads and Maritime Services displayed the Review of Environmental Factors and concept design for the Mount Ousley interchange between Thursday 16 November and Friday 15 December 2017. During the display period we received 130 submissions and a total of 236 separate comments. Read what the community had to say on the online tool.

The environmental assessment for the Mount Ousley Interchange is now complete and the Submissions Report (PDF, 1.23Mb) has now been published. The report answers questions raised by the community during the consultation period last year and has proposed a few design changes. It also considers additional consultation that took place around noise management during and after construction.

Next Steps

The project has achieved planning approval. Subject to funding, the next stage will be to prepare the detailed design for the project. Timing and funding for construction of the interchange upgrade is still to be confirmed.

The project

The proposed interchange would replace the existing intersection, and improve safety, reduce traffic congestion and provide for future traffic growth.

In response to ongoing consultation and investigations, we have continued to improve the design of the proposed interchange.

Key changes since the preferred option include:

  • new northbound exit from the motorway
  • additional heavy vehicle safety ramp
  • finalised commuter car park location with additional parking spaces and improved access
  • extended pedestrian and cyclist connections
  • relocation of the southbound entry to the motorway
  • new service road between Mount Ousley Road and University Avenue
  • closure of the southbound University Avenue exit from the motorway. Motorists would use the Mount Ousley Road exit and the service road.

Key benefits:

  • improved travel times
  • safer access to and from the motorway to Mount Ousley Road
  • improved access to the Wollongong CBD and University of Wollongong
  • improved safety by separating cars and heavy vehicles travelling down Mount Ousley
  • improved amenity for pedestrians and cyclists
  • reduced vehicle operating costs
  • provides for future traffic growth.
Benefits of this project: Improve pedestrian safety, better and more reliable trips, easing congestion, improving traffic flow.
