A major upgrade to one of the Illawarra’s most critical freight corridors has reached a new milestone, with the first heavy vehicle safety ramp now open as part of the Mount Ousley interchange project.
The $405 million development is designed to improve safety, connectivity and efficiency along a route used by more than 50,000 vehicles each day, including a significant volume of freight traffic.
For transport operators navigating the steep descent into Wollongong, the new infrastructure provides an immediate safety benefit while broader works continue.
What does the new Mount Ousley interchange ramp deliver?
The newly opened safety ramp is engineered to provide a controlled stopping area for trucks and buses experiencing brake failure.
Stretching 220 metres in length and five metres wide, the ramp is designed to safely accommodate B-doubles up to 26 metres.
It features a gravel arrestor bed and concrete barriers, allowing vehicles to decelerate gradually and come to a safe stop.
NSW Minister for Roads Jenny Aitchison said the ramp addresses a critical risk point on the corridor.
“If something goes wrong on that descent, drivers need somewhere safe to go. That’s exactly what this ramp provides,” Aitchison said.
Why is the Mount Ousley interchange important for freight?
Mount Ousley Road is a key access route linking the Illawarra to the Princes Motorway and broader freight networks.
It serves as a primary gateway for goods moving to and from Port Kembla, making reliability and safety essential for supply chain performance.
The Mount Ousley interchange is designed to reduce congestion, improve traffic flow and enhance safety for both freight and passenger vehicles.
Federal Minister Catherine King said the project is critical for regional connectivity.
“This is a significant investment in the Illawarra, improving safety and reliability on one of the region’s busiest highways,” King said.
How is construction progressing on the Mount Ousley interchange?
Construction is advancing across multiple components of the project, with major bridge structures now taking shape.
Sixteen pre-cast concrete girders have been installed to form part of the bridge connecting Mount Ousley Road over the heavy vehicle bypass.
Additional girders will support a shared path over the southbound access road, alongside ongoing works on bridge decks, drainage and approach infrastructure.
Recent night works have also delivered pavement connections, new signage gantries and drainage improvements to enhance safety in wet conditions.
NSW Minister Ryan Park said the visible progress reflects growing momentum on the project.
“This is an important milestone for a project that will deliver safer, more reliable journeys across the Illawarra,” Park said.
What does this mean for the Illawarra region?
Beyond freight efficiency, the Mount Ousley interchange is expected to support long-term regional growth.
Improved access to Wollongong and surrounding areas will benefit commuters, industry and tourism, while enhancing connections to key economic hubs.
NSW Minister Paul Scully said the upgrade will strengthen the region’s transport network.
“The new interchange will improve connectivity for motorists, freight and active transport users, while making this key gateway safer and more efficient,” Scully said.
The project remains on track for completion in 2028, with staged benefits already being realised as construction progresses.
