JUN 2020Work to start on 15 June

Transport for NSW will complete work to reinforce and strengthen the slope on Lawrence Hargrave Drive at Stanwell Park. This work is essential to keep the road safe and open to traffic in the long term.

Based on community feedback we will carry out work over an eight-week period. This option minimises impacts on the community and allows the work to be completed safely and efficiently.

Work will be carried out from 9am 15 June until 7pm 9 August. Transport for NSW has adjusted work dates for this project to accommodate urgent rail maintenance on 13 and 14 June. This will help to minimise impacts to community members making essential journeys while ensuring the safety of all transport users. We apologise for any inconvenience to the community.

During this work, Lawrence Hargrave Drive will be closed 24/7 in both directions between Lady Wakehurst Drive/ Otford Road and Chellow Dene Avenue.

The road will be closed in both directions and detours will be in place via the M1 Princes Motorway and Princes Highway (Bulli Pass) until work is complete, adding up to 45 minutes to travel times.

Residents between Chellow Dene Ave and the top of the hairpin bend will have access to their properties at all times during this work.

For more information on detour routes and resident access please view the Lawrence Hargrave Drive, Stanwell Park – detour map June - August 2020 (PDF, 539Kb).

Thank you for your patience while we carry out this essential work.

Project information

Transport for NSW is providing additional transport during this work to help minimise the impact on the community, including:

  • Additional stops at Stanwell Park station. On weekday mornings two existing services travelling to Central will temporarily stop at Stanwell Park, and on weekday afternoons one existing service from Central will temporarily stop at Stanwell Park.

    On weekends express services will make temporary stops at Stanwell Park to increase train services during the road closures.

    Train timetable information is available at transportnsw.info.
  • Shuttle bus between Stanwell Park and the train station. We will operate shuttle buses to transport Stanwell Park residents to and from train services. The shuttle buses will be operating on weekdays between 6am and 9pm, Saturdays between 7.30am and 6.30pm and Sundays between 8.30am and 5pm.

For more information including a map of the route, bus stops and service frequency please see our updated map (PDF, 380Kb) and timetable (PDF, 60.5Kb).

  • School shuttle buses.

    We have changed existing school bus services for children attending primary schools on the other side of the closure.

    These arrangements will be in place during this work to help minimise the impact of the closure for families living in and around the Stanwell Park area.

    Schools included in these arrangements are:

    • Holy Cross Catholic Primary School
    • Shire Christian School
    • Stanwell Park Public School
      The services will travel via the detour route and will be running about one hour earlier/ later.

      For more information please view the School bus services Fact Sheet (PDF, 120Kb) or visit our Routes and timetables website for bus stop locations and timetables.
  • Community members can also use existing Route 15 bus services to travel between Helensburgh train station and the Helensburgh area.

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.

Consultation period 2 (November - December 2019) consultation report (PDF, 404Kb)

  • 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.
