Milton Ulladulla bypass


Project overview

The $940 million Milton Ulladulla bypass will deliver safer and more reliable journeys along the Princes Highway by bypassing the Milton and Ulladulla town centres. The bypass will take the flow of 'through' traffic away from these town centres, reducing travel times.

Latest news

Feb 2023 – Northern connection in the vicinity of Little Forest Road

Transport for NSW would like to assure the community that the design and location of the northern connection of the Milton Ulladulla bypass is still being developed as investigations and planning continue to determine the exact location and access type.

The community will continue to be consulted throughout this process. A connection will be located in the vicinity of Little Forest Road as outlined in the refined corridor for the bypass, released by Transport for NSW in October 2022.

Transport for NSW met with property owners within the study and investigation area of Little Forest Road in November and December last year, and discussions are ongoing.

Transport for NSW is not aware of any meetings with property owners about building a roundabout on private property. More information about the bypass connections and design features will be released following the completion of the concept design and environmental assessment.

Transport for NSW looks forward to receiving further feedback from the community and residents in coming months.

Oct 2022 – Refined corridor

A refined corridor (PDF, 563Kb) for the Milton Ulladulla bypass is now available and the location of the northern and central connections confirmed.

The corridor has been refined to accommodate three connections to the existing Princes Highway and minimise impacts to the environment where possible. It provides a better opportunity to connect the bypass to local roads and town centres, supporting access to local businesses, services, and homes.

The northern connection will be in the vicinity of Little Forest Road. The bypass will include a central connection that will link to the Princes Highway via an extension of Bishop Drive at Ulladulla. The southern connection, which was confirmed in September 2022, is a two-lane roundabout, located to the north of Canberra Crescent at Burrill Lake.

For more information about the refined corridor view or download the latest community update (PDF, 1.55Mb).

Work is continuing on the concept design and environmental assessment, and once complete, more information about the bypass connections and design features will be released and the community will have opportunities to provide feedback.

We are working on the concept design and once complete, more information will be available.

Sep 2022 – Southern connection confirmed

Transport has identified the southern connection of the Milton Ulladulla bypass will be a two-lane roundabout, located to the north of Canberra Crescent at Burrill Lake. It will include a northbound bypass lane to provide uninterrupted access to the bypass for northbound traffic.

The draft design as shown below aims to minimise impacts to properties, the Burrill Lake township, and the environment. The design will ensure the southern connection enables flexibility for any future upgrades at Burrill Lake.

Sep 2022 – Southern connection confirmed and report released

Following significant consultation and investigation it has been confirmed that the southern connection to Milton Ulladulla bypass will be a roundabout just north of Canberra Crescent at Burrill Lake.

Balancing the needs of the whole community is always difficult, however reducing congestion currently experienced in the Milton and Ulladulla town centres and moving ahead with our plans to deliver a safer, more efficient and better connected Princes Highway is our priority.

Assessment of draft strategic options for the southern connection of the bypass was in scope for the Burrill Lake Co-Design Committee, and we recognise the challenging decisions faced by this group. The Co-Design committee has been an important part of the community engagement, and we acknowledge that the committee did not make a recommendation on their preferred option for the bypass southern connection or any upgrade of the Princes Highway at Burrill Lake.

Throughout the Co-Design process, we have listened to the Committee members and has taken their views, together with feedback from the wider community, key stakeholders and subject matter experts in landing on our decision for the intersection type location of the southern connection.

Following discussions with members of the Burrill Lake Co-Design committee, the process and outcomes report (PDF, 12.8Mb) has been finalised and can be viewed.

The focus is now on continuing investigations within the Milton Ulladulla bypass corridor to progress the project. This work will inform the concept design and the environmental assessment.

In the short term, important safety upgrades will be carried out south of Ulladulla to ensure safer and more efficient journeys for motorists including additional overtaking lanes, intersection upgrades, shoulder widening, and rest area upgrades.

Jul 2022 – Planning continues for the bypass

Planning for the Milton Ulladulla bypass continues. Environmental, field and site investigations, such as geotechnical, biodiversity and Aboriginal cultural heritage investigations, are ongoing.

Project information


The Princes Highway is a critical link between Sydney and the Illawarra Region with the NSW South Coast down to the Victorian border. It provides vital connections between towns and regional centres and is an important freight link. The Princes Highway connects key east-west road corridors and is a significant route for inter-regional business, tourism and leisure travel.

The proposed Milton Ulladulla bypass is a priority project and part of Transport’s 20 year plan to deliver a safe, reliable, efficient and connected transport network. The proposed Milton Ulladulla bypass aims to substantially reduce travel time and congestion, particularly during holiday periods. It would improve road safety after 111 crashes were recorded in the existing highway corridor through Milton and Ulladulla in a five-year period to 2018. The bypass would enhance the liveability within the Milton and Ulladulla town centres and enhance the appeal of the area.

The aim of the proposal is to upgrade the Princes Highway to provide a bypass of the Milton and Ulladulla town centres, delivering safer and more reliable journeys on the South Coast as part of the Princes Highway Upgrade program.

The proposed Milton Ulladulla bypass would:

  • Improve network safety for all road users
  • Improve traffic efficiency and connectivity to support regional economic development, tourism and freight
  • Improve transport network resilience
  • Enhance the amenity and liveability of Milton and Ulladulla and connected communities.

Next steps

Transport for NSW is progressing planning for the Milton Ulladulla bypass. Since the preferred corridor was announced in June 2021, Transport has been developing the concept design and preparing the environmental assessment to identify potential impacts.

The Australian Government has made an additional $352 million commitment announced in the 2022/23 Federal budget for the Milton Ulladulla bypass, taking the total Australian Government commitment for the Milton Ulladulla bypass to $752 million.

The NSW Government announced an additional $10 million for the bypass as part of the 2022-23 NSW budget. This will go a long way towards the construction of the preferred strategic corridor. A timeframe for construction is yet to be confirmed.
