Western Sydney Infrastructure Plan
Western Sydney Infrastructure Plan (WSIP) is an A$4.1 billion 10-year road investment program in Western Sydney, New South Wales, jointly funded by the federal government ($3.3 billion) and the New South Wales state government. Originally introduced in April 2014 as a $3.5 billion program consisting of key road upgrade projects in Western Sydney, particularly in the south west surrounding the future Western Sydney Airport, the program scope was later expanded and funding was increased to $4.1 billion. The funding is now split among:
- The Northern Road Upgrade - $1.6 billion
- Bringelly Road upgrade - $500 million
- M12 Motorway - $1.75 billion
- Werrington Arterial Road - $50 million
- Glenbrook Intersection at Ross Street - $5.6 million
- Local Roads Package - $200 million
The plan was to take place over 10 years, starting with the Bringelly Road upgrade which commenced construction in January 2015. As of 2023, the only remaining component that is yet to be completed is the M12 Motorway, which is under construction and set to be completed prior to the completion of the new airport in 2026.
