Great Northern Highway and Pinga Street

What's Happening 

To support the development of Lumsden Point, we’re upgrading Great Northern Highway and Pinga Street with:

• Construction of a new roundabout underpass, connecting Pinga Street to the new Lumsden Point Access Road
• Construction of two, 15 metre single span structures (bridges) over the new roundabout interchange (providing four lanes over the roundabout); and
• Construction of four new access ramps on to, and off of, Great Northern Highway along with new turning pockets at the Lumsden Point Access Road.

Structural work on the two bridges is now complete, along with pavement and surfacing work on Great Northern Highway, and the northern ramps. Barrier installation and kerbing is also complete.

Work to install lighting is progressing, and work to construct the new roundabout and complete the southern ramps will commence in August.

Benefits

When complete the upgrades will:

• significantly improve traffic flow and help reduce congestion at Pinga Street, enhance acceleration opportunities and ensure adequate sight distance for all road users.
• facilitate safer entry and exit at Lumsden Point Access Road for all vehicles;
• facilitate the safe movement of OSOM loads and help accommodate increased traffic volumes from Lumsden Point, improving road safety and travel amenity for all road users in the Wedgefield area.

Temporary Road Closure – 10 August to mid-October 2025

To facilitate construction of the remaining Lumsden Point Interchange works, temporary traffic changes are planned for Great Northern Highway and Pinga Street.

Access to Wedgefield

• Pinga Street will be closed from Moorambine Street to Great Northern Highway - see Travel Map
• All road users entering or exiting Great Northern Highway to/from Wedgefield will be detoured via Hematite Drive - see detour map.

Traffic flow on the newly constructed Great Northern Highway

• All traffic will be shifted onto the newly constructed Great Northern Highway (Lumsden Interchange) over the bridges.
• One lane open in each direction over the bridges.
• Restricted access permitted for Pilbara Ports personnel and Contractors to Lumsden Point via the newly constructed northern on/off ramps.

Traffic management including speed reductions remain in place and road users are reminded to please be roadwork aware, slow down and take care.
