Gundaroo Drive duplication stage 1

Gundaroo Drive currently carries up to 23,000 vehicles a day, providing an important connection for Gungahlin residents travelling to Belconnen and south Canberra.

Roads ACT have identified the duplication of Gundaroo Drive as an upgrade requirement to improve safety, ease increasing congestion in the Gungahlin region, and manage traffic growth.

Stage 1 duplication works involve the construction of a second carriageway on Gundaroo Drive from Gungahlin Drive to the Mirrabei Drive/Anthony Rolfe Avenue roundabout. This section of the road has been prioritised due to accident trends and key areas of congestion.

Duplication of this section of the road will improve safety and relieve congestion in the growing Gungahlin region. On-road cycle lanes will be provided including safe passage around the two roundabouts on this section of road. Public transport will also benefit with the upgrade to the intersection of Gundaroo and Gungahlin Drives to include priority lanes for buses travelling in both directions along Gundaroo Drive.

This project has also been expanded to include a new signalised intersection at Gundaroo Drive and Mirrabei Drive/Anthony Rolfe Avenue and an additional southbound lane on Mirrabei Drive from Paul Coe Crescent.

Construction update

The traffic lights at the newly signalised intersection of Gundaroo Drive and Mirrabei Drive/Anthony Rolfe Avenue became operational in October 2018 and four lanes of traffic between the intersection and Gungahlin Drive were opened.

The project team is now completing minor works, including landscaping.


Note there are numerous projects on arterial and major roads in Gungahlin that are scheduled to be under construction at the same time and the ACT Government would like the thank motorists for their patience while these important works are undertaken.
