FEB 2020Work to start on Tuesday 9 June

Transport for NSW would like to thank the community for providing feedback on plans to close Lawrence Hargrave Drive at Stanwell Park for this essential work.

Based on community feedback it has been determined that the work will be carried out over one eight-week closure in the winter months. This option minimises long term impact on the community and allows the work to be completed safely and efficiently.

Work will start on Tuesday 9 June 2020 for one eight-week period and will finish on Tuesday 4 August 2020. No work will be carried out over the June long weekend, weather permitting.

We are inviting the community to register their interest for shuttle bus services by Friday 13 March 2020.

This information will help us plan and schedule shuttle bus services and timetables.

We will carry out a community drop-in session in the coming months to keep the community informed about this project and provide further information about shuttle buses and train timetables.

Project information

Lawrence Hargrave Drive crosses the Illawarra Escarpment at a geotechnically unstable location. It is prone to slope movement creating cracking in the road surface and shoulders.

We have conducted in-depth geotechnical investigations and as a result, we have identified a number of sites between Otford Road and Chellow Dene Avenue where we need to carry out work to stabilise the slope and reduce the risk of land slips.

Work to be carried out includes installing soil nails and other remediation work to reinforce and strengthen the ground.

We will also construct a concrete retaining wall and improve drainage to assist with groundwater run-off, which can contribute to cracks in the road surface.

This work is essential to keep the road safe and open to traffic in the longer term.

The community was invited to have their say on potential closures on Lawrence Hargrave Drive while essential safety work is carried out.

Transport for NSW developed alternative options to carry out this work based on the feedback received. We invited the community to complete a further survey to identify their preferred option.

The options available for feedback were:

Option AOption BOption COption D
Two stages of four-week road closures (during winter months) One eight-week road closure (during winter months) 16-day full road closure (during winter school holidays)

Plus six to eight months:

  • full road closures on weekdays from 9am-3pm;
  • only one lane open to traffic (under alternating traffic flow) at all other times until work complete

16-day road closure (during winter school holidays)

Plus four to six months:

  • full road closures on weekdays from 9am to 3pm;
  • full road closures from Sunday to Thursday at night from 8pm to 4am;
  • only one lane open to traffic (under alternating traffic flow) at all other times until work complete

A map (PDF, 184Kb) showing the one lane alternating traffic arrangements included in Option C and D is available to view.

Transport for NSW consulted the community around four options from November to December 2019 on plans for the project. The community was asked to provide feedback on closing the road in two four week stages with work taking place 24 hours a day. Following the feedback from this consultation we developed four options for further community and stakeholder feedback.

The second consultation received 720 responses, 717 of these respondents selected a preferred option to carry out the work.

The consultation was carried out to gain a better understanding of the Stanwell Park area and how our customers use this stretch of road, to help inform plans to carry out the essential slope stabilisation and maintenance work on Lawrence Hargrave Drive.

  • The work will reduce the risk of land slips on the downhill slope.
  • Slopes will be strengthened using a variety of methods.
  • Cracks in the road surface will be repaired and drainage improved to reduce water pooling
  • It will address the risk of a potential long-term closure of Lawrence Hargrave Drive due to land slippage.

We have held discussions with all emergency services and will continue to work with these and other affected stakeholders to deliver effective incident management plans.

We are also working directly with authorities including Wollongong City Council, NSW Train Link, the freight industry, emergency services, schools and local businesses.

We thank the community for their patience while we carry out this important safety work.
