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.
Construction of a new flyover and interchange at the Monaro Highway and Lanyon Drive intersection is now underway.
As part of the project, 40 bridge girders are needed to be lifted on to the piers to form part of the bridge structure. So far, 20 bridge girders are in place on the northern side of the project.
To allow for construction to progress on the project, Lanyon Drive between the northbound and southbound carriageways of Monaro Highway will be closed from 7pm, Friday 17 October to 5am, Monday 20 October 2025.
This weekend closure will allow for concrete girders to be safely lifted on to the bridge piers over Lanyon Drive.
To minimise traffic impacts, the closures will commence after the PM peak on a Friday evening, and the road will be reopened prior to the AM peak on the following Monday morning, weather and site conditions permitting.
During the closure, there will be detours through the Hume industrial area along Sheppard Street to access Monaro Highway, with forecast impacts of approximately five minutes.
An alternative route for road users travelling from Jerrabomberra to north Canberra is to turn right onto Lanyon Drive at Tompsitt Drive and then use Canberra Avenue.
These closures improve the safety of both road users and project workers while 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.
Further weekend closures will be required for bridge construction and works including a new stormwater line and pavements near the northbound carriageway intersection. Dates of these works will be updated over the coming months.
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 3-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 onto 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.
