Road rehabilitation


Current update

Sulwood Drive

Work has been underway to rehabilitate Sulwood Drive between Athllon Drive and the Mannheim Street intersection and from the Mannheim Street intersection to the Tuggeranong Parkway (map below).

All major works for the road rehabilitation are now complete. Minor works are expected to be complete by the end of March 2026, weather and site conditions permitting,

The speed limit is reduced to 40km/h to facilitate final works.

We thank the community for their patience whilst work is underway.

The ACT's road network is approximately 5,900 lane km in length and about 20 million m2 in area.

Road pavements deteriorate over time due to the impact of traffic, heavy vehicles and environmental factors.

As the road surface wears and ages, small cracks develop in the pavement. This allows water to enter the underlying surface. Water infiltration, combined with the continual stress from traffic, weakens the pavement. This can result in potholes, major cracks, pavement deformation and ultimately road failure.

Pavement rehabilitation involves removing and replacing all road material. This work has been completed at sites across Canberra, including:

  • Kings Highway from the Mill Post Road intersection to the ACT and NSW border
  • David Walsh Avenue
  • Isabella Drive
  • Northbourne Avenue
  • Tarra Place.

Construction

  • Pialligo Avenue (Oaks Estate Road/Pialligo Avenue intersection to the NSW border), Majura
  • William Hovell Drive
  • Gungahlin Drive (Well Station Drive to Barton Highway), Mitchell.

Foam bitumen stabilisation

Throughout our rehabilitation program we are looking to use more environmentally sustainable products. We were the first jurisdiction in Australia to use foam bitumen stabilisation for this kind of work.

In this process, asphalt millings are sent to the asphalt plant and returned with the first layer of recycled asphalt. The remainder of the millings are mixed with the existing pavement layers below and stabilised with foam bitumen and lime. Once the work is complete, the recycled asphalt is placed followed by the final layer of road surface. This is a sustainable process where no materials are wasted.

We have used this on 2 sections of Northbourne Avenue and on David Walsh Avenue in Forde. See the completed projects page for more information about these projects.
