The Mount Ousley interchange has been designed to improve safety for road users by separating light and heavy vehicles, improve travel time and efficiency for all motorists, support growing freight movements, and improve access to and from the M1 Princes Motorway and Wollongong CBD.
A Review of Environmental Factors (REF) for the project was completed and placed on public display in 2017 with the project’s Submission Report published in April 2018.
Following this, an Addendum Review of Environmental Factors was prepared to document the potential environmental impacts of early utility works outside of the original REF proposal area. You can view the REF and Submissions Report on the project website.
During 2023, refinements were made to the scope and design to ensure the project achieve a value for money solution which delivered core project objectives.
Fulton Hogan has been awarded the contract to design and build the Mount Ousley interchange project. Early work is underway with major work planned to start in late 2024.
