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 in planning for this project.

Updates and announcements

The concept design and environmental assessment for the proposal is now on display. The community is invited to provide feedback until Friday 15 December 2017.

Over the past 12 months we have been carrying out a number of environmental studies for the proposed interchange. The benefits and impacts of the proposal and proposed measures to manage any potential environmental impacts are addressed in the review of environmental factors and its appendices.

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.

Next steps

The project team will consider feedback received during the display in finalising the design for the proposed interchange.

A submissions report summarising feedback received during the display will be available in early 2018.

Timing and funding for construction of the interchange upgrade is still to be confirmed.
