Albion Park Rail bypass - Princes Highway upgrade


Project overview

Transport for NSW has completed an extension of the M1 Princes Motorway between Yallah and Oak Flats to bypass Albion Park Rail. The Albion Park Rail bypass is a $630 million project funded by the NSW Government that completes the 'missing link' for a high standard road between Sydney and Bomaderry. It is an important freight, bus and tourist route. The bypass was opened in October 2021, and work was completed early 2022.

JAN 2022Oak Flats interchange

Transport for NSW is continuing to monitor and review the operation of the Oak Flats interchange in response to feedback received from the community. A number of changes have been implemented to improve the safety and efficiency of the interchange.

Changes to linemarking, new signage and Portable Electronic Message Boards have been installed to assist road users to select the correct travel lane.

We have also been carrying out video and physical monitoring since the traffic lights at Oak Flats interchange were switched on and have made changes to the sequence of traffic lights to ensure a smoother flow of traffic in the area.

We will continue to monitor the operation of the signalised interchange and make changes as needed to ensure safe and efficient journeys through the area for our customers.
