Campbelltown Road upgrade


Project overview

Transport for NSW is upgrading Campbelltown Road between Hume Highway/Camden Valley Way, Casula and Brooks Road, Denham Court. Stage one is underway and Stage two is being planned and designed.

Project information


Transport for NSW is upgrading 5.4 kilometres of Campbelltown Road between Camden Valley Way, Casula and Brooks Road, Denham Court.

The upgrade will meet the needs of the areas current population and the anticipated increase in traffic from the development of the area.

The project is being jointly funded by the NSW Government Housing Acceleration Fund and Landcom (previously known as Urban Growth NSW).

Key features of the project

The Campbelltown Road upgrade will:

  • widen Campbelltown Road from one lane each direction to two, with the potential to add a third lane if needed in the future
  • improve six intersections along Campbelltown Road by upgrading or installing traffic lights
  • build an off-road shared pedestrian/cyclist path
  • install designated turning lanes and bicycle and pedestrian crossings at traffic lights.


  • Improved safety for motorists by:
    • Building new intersections with traffic lights to improve traffic flow and road safety
    • Providing a central median to separate traffic
    • Providing turning lanes at intersections
  • Improved safety for cyclists and pedestrians by providing an off-road shared path
  • Improved travel times
  • Access to the Edmondson Park town centre from Campbelltown Road
  • Improved access and travel times for road freight in Sydney’s south west

Traffic modelling

Transport for NSW maintains a strategic traffic forecasting model using software known as EMME (Equilibrium Model/Multimodal Equilibrium). EMME is a travel demand modelling system used for urban, regional and national transportation forecasting.

Transport for NSW uses transport forecasting software (EMME), to undertake traffic modelling and forecasting of road schemes with wide-reaching network impacts, and to examine the effects of significant new residential or employment land releases, major incidents, tolling or other strategies.

In basic terms the model comprises a base road network and a number of zones, similar to suburbs or parts of suburbs. For each of these zones, Transport for NSW receives information of population and employment forecasts from the NSW Bureau of Transport Statistics. This information also includes information about trips between zones. In modelling terms this is known as origin and destination information. The model generates trips between zones based on the land use information and trip patterns. The trips are assigned dynamically within the EMME model to the route or combination of connecting roads, that provides the overall shortest travel time between the starting zone, the origin, and the ending zone, the destination.

Further information can be found on the Bureau of Transport Statistics webpage, in particular, the following documents:

The models are calibrated for the 7am to 9am and 4pm to 6pm peak hours based on actual survey traffic data for the principal routes within the model to ensure they are providing an accurate representation of real world travel patterns.

Once the base year has been established and successfully calibrated, travel patterns can be forecast for future years. The future year forecasts rely on the population and employment forecasts and assumptions about the state of the future road network.  For example, modelling of the South West region of Sydney for 2011 would include a two lane undivided Camden Valley Way. Modelling for 2016 would include a four lane divided Camden Valley Way.

Details of existing and predicted population growth forecasts, employment growth forecast, modes of traffic and Annualised Average Daily Traffic counts and forecasts are also provided in Appendix B of the REF. Transport for NSW has undertaken 'sensitivity analysis' in anticipation of potential traffic forecast variation.

What's happening now?

Transport for NSW has started work on the Campbelltown Road upgrade – Stage 1 - between Zouch Road and Ingleburn Gardens Drive, Bardia.

Work began in September 2018 and will be completed by the end of 2020.

Transport for NSW has awarded the major construction contract for Stage 1 to Burton Contractors Pty Ltd.2020.

The rest of the Campbelltown Road upgrade will be built in stages, subject to funding being made available.

Community information

Community consultation

Before beginning construction, Transport for NSW consulted with residents, businesses, local council and other key stakeholders on the proposed plan to upgrade Campbelltown Road.

Based on community feedback we will be:

  1. widening the roundabout at Denham Court Road, Campbelltown Road and Dickson Road to two lanes to improve traffic flow and ease congestion
  2. installing a right turn bay from the northbound carriageway of Campbelltown Road onto Bloomfield Road
  3. reducing the width of Campbelltown Road south of Zouch Road to minimise the impact on nearby property owner while still keeping the road will remain two lanes in each direction

Review of Environmental Factors (REF)

The formal comment period for the Campbelltown Road upgrade Review of Environmental Factors (REF) and concept design has closed and the Submissions Report is now available.

Comments, feedback and suggestions were sought between 15 April 2013 and Friday 5 July 2013 (13 weeks in total) after community members requested more time to consider the information that had been made available during the display period. Late submissions were also accepted for inclusion in the submissions report until 22 October 2013.

Project team members attended information meetings hosted by Denham Court Association on 20 May and Campbelltown City Council on 24 June 2013.

Further information provided as a result of these information sessions is available.

Transport for NSW provided information to address the concerns raised by the community in the attached letter to residents and Questions and Answers, issued on 24 May 2013.

At the 24 June 2013 community information session, Transport for NSW was asked to provide some additional information about traffic modelling and the assumptions which informed the traffic modelling carried out for the proposal.

Transport for NSW was also asked to publish the posters used at the information evening so this additional information could be viewed by the public. These posters are now available.

Transport for NSW would like to thank everyone who provided comments or asked questions and attended the community information sessions. We appreciate hearing your concerns first hand and encourage the community to continue to engage with us about this proposal.

Community information sessions

Project team members held four community information sessions for community members to drop by and ask questions or leave feedback with the team. These were held at:

  • Narellan Town Centre on Thursday 11 April 2013, from 3pm to 7pm
  • Ingleburn Public School Hall on Saturday 13 April 2013, from 11am to 2pm
  • Leppington Progress Hall on Thursday 2 May 2013, from 3pm to 7pm
  • Crossroads Homemaker Centre, Casula on Saturday 4 May 2013, from 11am to 2pm.
