Transport for NSW has carried out detailed traffic investigation and modelling to understand the future traffic volumes and split between the existing highway and the proposed bypass.
Our modelling indicates that traffic volumes on the bypass do not reach levels where dual carriageway would be justified.
The proposed bypass has been designed with flexibility and can be upgraded to dual carriageway in the future if traffic volumes reach the point where it is viable.
The New England Highway is a major freight and commuter route forming part of the Sydney to Brisbane Corridor of the National Land Transport Network and the primary route connecting the Upper Hunter with Maitland and Newcastle.
Around 26,000 vehicles, including more than 3700 trucks, travel through Singleton each day. Traffic has increased in recent years, with coal mining industry commuters and heavy vehicles identified as a major contributor. The area is already experiencing high levels of congestion, and traffic volumes are expected to increase over time in line with population growth.
A New England Highway bypass at Singleton would address current congestion and future traffic demands.
The proposed bypass would have region wide benefits such as:
- Improve travel reliability on the New England Highway through Singleton, particularly for road freight supporting the Upper Hunter and the North West New England region
- Improve the amenity of Singleton by removing freight traffic
- Improve road safety for through and local traffic in Singleton
- Support future traffic growth along the New England Highway associated with planned land use in the Upper Hunter area
- Provide access for oversize over mass vehicles along the New England Highway.
- About eight kilometres of new highway (the bypass) with a single lane in each direction
- Connection with the New England Highway at the southern end of the bypass (the southern connection) including a southbound entry ramp and northbound exit ramp
- A 1.7 kilometre long bridge over the Main North railway line, the Doughboy Hollow and Hunter River floodplain, Army Camp Road and Putty Road (bridge over the floodplain)
- Connection to Putty Road including a northbound entry ramp and southbound exit ramp (the Putty Road connection)
- Connection with the New England Highway at Gowrie Gates consisting of a southbound entry ramp and northbound exit ramp. The northbound exit ramp would connect to the New England Highway via a new roundabout intersection at Maison Dieu Road
- A 1.7 kilometre northbound climbing lane between Gowrie Gates and the northern connection
- Connection at Magpie Street including providing access to the nearby industrial area (the northern connection), consisting of a southbound entry ramp, southbound exit ramp and northbound entry ramp.
In 2015 a number of strategic corridor options for the singleton bypass were placed on public display. These were based on a number of studies and strategies carried out by Transport for NSW.
Following community feedback and a value management workshop that included representatives from Singleton Council, businesses, community groups and other government agencies, these options were shortlisted to three. After considering traffic impacts, environmental issues and community feedback, a preferred route option was announced as the preferred option for the Singleton Bypass project in 2016.

A concept design for the Singleton Bypass has been developed and a Review of Environmental Factors (REF) has been carried out. The concept design and REF was displayed for public comment from December 2019 until 1 March 2020.
Transport for NSW is now preparing a submissions report that summarises the comments made and its responses.
The next step is to determine the REF which confirms the project meets all the environmental requirements. This step considers all feedback received, includes any recommendations that need to be made and then provides approval to proceed from an environmental point of view. Once this is in place, the detailed design will be developed. The community will be kept informed as the project progresses.
The NSW Government has committed $92 million towards the Singleton bypass under Rebuilding NSW and allocated $2.7 million in 2019-20 to continue development of the project.
Timing for construction of the bypass has not been confirmed and is subject to approval and funding availability.
Transport for NSW has identified properties impacted and potentially impacted by the project. We have and will continue to consult directly with all owners. We will contact you directly if we need to enter your property to carry out field investigations to help gather information needed in the development of the project.
Transport for NSW may also need to acquire privately owned land as part of developing the project. A property is described as being 'directly affected' by a project when Transport for NSW needs to acquire part or all of it in order to deliver the project. Transport for NSW will, at the relevant time, contact owners of affected properties.
Further information relating to land acquisition is available here: https://www.rms.nsw.gov.au/about/what-we-do/land-acquisition.html
The New Singleton Bypass project will provide flood immunity for a 1 in 100 year flood event.
Interaction with groundwater is anticipated during the construction of bridge piles and piers for the proposal. To minimise the potential of encountering groundwater, the pile holes would be installed by advancing steel casing into the ground as they are drilled. The steel casing will pass through one to two metres of gravel below the existing water table. Once the casing has been advanced to the bedrock, groundwater is generally not expected to be encountered.
The operation of the proposal would not result in substantial changes to the recharge of groundwater within the proposal area and therefore no ongoing impact to groundwater users is anticipated.

Information for the community
Transport for NSW will continue to work with the community and stakeholders during the planning of the Singleton Bypass to understand issues and minimise potential impacts. All community and stakeholder feedback on the project is welcome.
We will liaise directly with any property owners potentially affected by the Singleton Bypass proposal, as well as engage with the broader community and other stakeholders.
Visit the Singleton project page to sign up for updates and to find out more information, including our interactive portal.
Feedback received by the community on the REF will inform the development of the proposal.
The public display has now closed for the concept design and review of environmental factors (REF) for the Singleton Bypass.
Thank you to the community members who took the time to consider our proposal and provide feedback.
We will now prepare a submissions report, which includes feedback received from the community and our responses.
The community will be informed when the report is published in the coming months.

What is an REF?
The REF describes the key features of the Singleton Bypass project and assesses the potential environmental and social impacts during construction and operation.
The REF document also makes recommendations on measures to manage and minimise potential impacts from the project.
The REF covers topics such as noise, vibration, traffic, air quality, flooding, Aboriginal and non-Aboriginal heritage, and socio-economic, agricultural property and biodiversity impacts.
The REF display is an opportunity for the community to make comment on the environmental impacts and mitigations for the proposed upgrade.
