Work is continuing on construction of a flyover and interchange at the Monaro Highway and Lanyon Drive intersection to improve safety, freight efficiency and commute times.
From 14 April 2025 there will be changed traffic conditions to support the demolition and construction of a new bridge over Dog Trap Creek.
Temporary traffic lights will be installed on the northbound lanes of the Monaro Highway at the Lanyon Drive intersection and lane changes put in place northbound to Dog Trap Creek bridge.
The traffic lights will allow vehicles on Lanyon Drive to safely turn north onto the Monaro Highway and light sequencing will be coordinated with other traffic lights in the area.
Road users travelling northbound, after the new temporary traffic lights, will see a change in lane configuration over Dog Trap Creek for the duration of the bridge work. These changes start from 14 April 2025 and are expected to be in place for approximately 15 months. These changed traffic arrangements will only impact northbound traffic.
During the peak travel periods the speed limit will remain at 60km/h. Outside of peak travel periods, the speed limit may be temporarily reduced to 40km/h as required.
Travel impacts and alternate travel options
The changed traffic arrangements will impact travel times throughout construction. This will be most significant in the morning peak periods where delays could be up to 8 minutes for northbound travel on the Monaro Highway and up to 10 minutes for westbound travel, towards Canberra on Lanyon Drive.
Road users travelling northbound towards Fyshwick, Symonston, Pialligo, Majura, Canberra City, and other suburbs are advised to expect delays of up to 8 minutes, particularly in the morning peak period.
The ACT Government recognises this is a major delay and has investigated alternative traffic management options. The traffic management plan that will be implemented is designed to have the least impact on traffic and ensure safety for all.
Alternative travel routes have been identified, however, it is acknowledged that additional traffic on the alternative routes will also impact travel time on those roads.
Road users coming from Queanbeyan, Jerrabomberra or Googong and surrounds heading to the airport or central Canberra can divert along the northern most section of Lanyon Drive, toward Canberra Avenue.
Road users coming from Tuggeranong or Royalla and surrounds and heading to the airport or central Canberra can divert along Johnson Drive, Ashley Drive and Yamba Drive.
Electronic signage will be installed on the Monaro Highway before the Isabella Drive turnoff and on Isabella Drive to advise road users of proposed work as well as regular updates.
The ACT Government will undertake ongoing monitoring of the changed traffic arrangements on the Monaro Highway as well as the overflow impacts on alternate routes. Traffic cameras will be installed on the temporary traffic lights and a live feed will be available to our Traffic Management Centre. Whenever possible, changes to the traffic light phasing will be made to try to ease overall congestion.
Road users are encouraged to rethink their routine including travelling outside of peak periods where possible. Some apps such as Waze and Google Maps can be used to identify the best travel time.
Construction of the flyover and interchange is expected to be completed at the end of 2026.
The Monaro Highway upgrade is jointly funded by the Australian and ACT Governments.
