NOV 2019Have your say on Lawrence Hargrave Drive

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

In July 2019 Roads and Maritime invited feedback on a proposal to carry out this work in two stages during 2020. We have reviewed all comments and have analysed the feedback.

Roads and Maritime has now developed alternative options to carry out this work based on the feedback received. We are inviting the community to complete a further survey to identify their preferred option.

The options are:

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.

You are invited to provide feedback by 5pm, Monday 16 December.

Drop-in sessions will be held at the CWA Hall - 15 The Drive, Stanwell Park, so the community can speak to the project team and find out more about the work and the options.

The sessions will be held:

  • Tuesday 26 November from 11am to 2pm
  • Monday 9 December from 5pm to 8pm

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.

Please provide feedback by 5pm, Monday 16 December.

Roads and Maritime consulted the community for a six week period from July – August 2019 on plans for the project. The community was asked to provide feedback on closing the road to complete the work in two four-week stages with work taking place 24 hours a day. The first four-week closure was proposed for February/March 2020 and the second in May/June 2020.

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 consultation report (PDF, 607Kb) is now ready to be viewed.

Key issues raised by the community included:

  • Concern around extended travel time
  • Concern around timing of the works during summer
  • The effect on traffic to local businesses
  • Requests to keep one lane open during this work.

After considering the feedback provided, Roads and Maritime will not proceed with the original proposal and is now carrying out further consultation with the community through a survey on alternative options.

  • 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.

Your feedback will help us determine how we will complete this work and to alert us to any issues or concerns you may have. Once we have reviewed survey results and feedback, we will update the community about the outcomes and work details. We expect to update the community in early 2020.

We will also work closely with residents who may be most impacted by the work and will discuss appropriate mitigation measures if required.

We will carefully consider your feedback and continue to keep you updated as the project progresses.
