Investigation work on Princes Highway at Mount Ousley interchange

20 September 2018

Parliamentary Secretary for the Illawarra and South Coast Gareth Ward MP has today announced that investigation work will be carried out from Monday 24 September along the Princes Highway, as part of preparation work for the Mount Ousley interchange.

Mr Ward said that the New South Wales Government had allocated $3 million to continue planning work for the M1 Princes Motorway interchange at the base of Mount Ousley.

“The project will result in improved travel times, safer access to and from the motorway to Mount Ousley Road, as well as improved access to the Wollongong CBD and University of Wollongong,” Mr Ward said.

“As part of the planning process, Roads and Maritime Services will carry out geotechnical investigations involving drilling boreholes and excavating test pits to identify the ground conditions.

“The investigation work will take place across an area from Highbank Place to University Avenue, along the Princes Motorway and take up to three months to complete.

“Work will be carried out on weekdays between 7am and 6pm, weather permitting. The community will be notified in advance of any work outside these hours.

“The majority of the investigation work will be outside of the road corridor and will not affect traffic.

“However, during the investigation period, there will be a few locations which will require temporary traffic changes and lane closures to ensure the area is safe for workers and road users.”

Access to private properties will be maintained at all times. Pedestrian walkways will not be impacted during this work.

Drilling will also take place in the commuter car park on Old Mount Ousley Road, which will impact on a limited number of parking spaces for up to five days.

Please keep to speed limits and follow the direction of traffic controllers and signs.
