Albion Park Rail bypass - Princes Highway upgrade

Transport for NSW is building an extension of the M1 Princes Motorway between Yallah and Oak Flats to bypass Albion Park Rail. The NSW Government is funding the $630 million project. The bypass would complete the 'missing link' for a high standard road between Sydney and Bomaderry. Motorists are expected to be driving on the new motorway by mid-2021, with the project on track for completion in late 2021.
