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, in conjunction with the newly-announced Western Sydney Airport project, 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. The last component to be completed was the M12 Motorway, which opened on 14 March 2026 and will be fully completed in mid-2026, prior to the completion of the new airport later that year.
