Australia’s Infrastructure – A list of Major Projects

Australia’s infrastructure is booming, with several significant projects in action across the nation. We have put together a list and brief description of 12 major projects currently in progress, all of which are responsible for boosting the local economy.

12 Major Projects:

1. WestConnex (NSW), $16 Billion

WestConnex is Australia’s infrastructure largest road project to ease congestion, create thousands of jobs, and connect communities.

Due to completion in 2023, WestConnex will provide a 33km traffic-light free motorway network. In-tunnel technology has removed congestion and taken the roads underground. Early indications show that air quality around the tunnels improves once the tunnels open. Construction of the projects has also created a skills legacy, with thousands of workers undertaking certified training to help staff future projects.

Project stages:

The New M4 – included 5.5km New M4 tunnels, which were completed in 2019. Motorists in this section are saving an average of 35minutes on their westbound peak time journey compared to Parramatta Road.

The M8 – opened in July 2020. The 9km twin tunnels connect the M5T Kingsgrove to the new interchange at St Peters, creating six hectares of new open space.

The M4-M5 Link Tunnels – 7.5km tunnels linking the new M4 at Haberfield with the M8 at St Peters.

The Rozelle Interchange – set to open in 2023. It connects the M4-M5 Link to Anzac and Iron Cove bridges. The interchange is being built almost entirely underground, freeing up space for a new 10ha regional park.
