As part of the WestConnex M8, a new above ground interchange has been built in St Peters. The site was
transformed from a contaminated landfill into a future-proofed state-of-the-art above ground motorway
network with important connections to future projects linking to the airport, southern Sydney and a second
harbour tunnel crossing.
Building St Peters Interchange was the catalyst for the remediation of the contaminated Alexandria Landfill
site which has now been transformed into accessible public space for the first time in decades.
Approximately 400,000m³ of waste has been treated, capped, and safely retained on site allowing for the
sustainable delivery of more than 6-hectares of accessible green space including 650,000 new trees, shrubs
The new green space is also the home to many of the public art installations from the WestConnex Public Art
Program – Canal to Creek.
