Monaro Highway upgrade traffic changes

The Monaro Highway is being upgraded to deliver improved safety, freight efficiency and faster and smoother travel for Tuggeranong, the Woden Valley and southern NSW.

There will be an off-peak weekend closure of Monaro Highway (southbound only) between Hindmarsh Drive and Lanyon Drive required. The closure is scheduled from 7pm, Friday 14 November to 5am, Monday 17 November 2025, weather dependent.

The closure is in place to allow reconstruction of pavement along sections of the Monaro Highway’s southbound carriageway (within the project area).

During the closure, the following detours will be in place:

• Travelling west on Hindmarsh Drive, left on to Mugga Lane and continue onto Monaro Highway.
• Travelling east on Hindmarsh Drive, right on to Canberra Avenue right on to Lanyon Drive and continue to Monaro Highway. NB: Heavy vehicles will be diverted to this detour.
• Travelling west along Canberra Avenue, left on to Sturt Avenue and Jerrabomberra Ave, right on to Hindmarsh Drive.

Traffic management will be in place during the closure to allow access for emergency services vehicles and access to the Alexander Maconochie Centre and ACT Government facilities along David Warren Road.

This closure improves the safety of both road users and project workers whilst works are undertaken.

Road users are reminded to follow all signage and directions from traffic controllers, and to be aware that reduced speed limits apply throughout the project site.

About the project

The Monaro Highway upgrade is part of a long-term series of road improvements that will create improved safety, freight efficiency and faster and smoother commutes.

It will also include:

• A new southbound flyover on the Monaro Highway over Lanyon Drive (including three-metre-wide sealed shoulders).
• The highway road pavement upgraded from David Warren Road, near the Alexander Maconochie Centre, through to Sheppard Street in Hume (including 3-metre-wide sealed shoulders).
• A new widened bridge on the northbound carriageway over Dog Trap Creek/Woden Creek just north of Lanyon Drive. This includes an improved northbound merge from Lanyon Drive on to the Monaro Highway.
• The new bridge structure will have Indigenous artwork applied to some of the external elements.

Construction of the flyover and interchange is expected to be completed by the end of 2026.

The Monaro Highway upgrade is jointly funded by the Australian and ACT Governments through the Infrastructure Investment Program.
