The NSW government’s massive infrastructure spend is expected to peak over the next year as the state continues to build its way out of the coronavirus pandemic, with construction soon set to begin on two new major road projects.

Tuesday’s state budget revealed an unprecedented $30 billion infrastructure spend within the next financial year, with $585 million allocated to the Gateway project, linking WestConnex and Sydney Airport, with work likely to begin within months.

The Gateway project was initially slated to be completed in 2023, but that was pushed to 2024 in November, when Premier Gladys Berejiklian tipped construction would begin in early 2021.

The start of work has now been pushed out by at least six months, with construction likely to begin before September. The motorway plays a critical role in the WestConnex, but is not budgeted within $16.8 billion project.
