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.

Construction of the temporary side track is complete with traffic diverted to the track in late November.

Excavation and ground improvement work for the Lumsden Point Access Road is mostly complete, with the majority of the new road now at subgrade level. Piling work at the bridge sites commenced in December 2024, with superstructure works to commence in early 2025.

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.

Road work impacts

All traffic on Great Northern Highway in Wedgefield is now being diverted to the temporary side-track. Road users are reminded to follow all traffic management directions and speed reductions. The temporary side track will remain in place until project completion, which is expected to be October 2025.
