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 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 involved 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 was 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 was 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. This will improve safety for pedestrians and cyclists. There are three main active travel community routes and an increasing demand for pedestrian and cyclist access to the nearby Yerrabi Pond District Park which have prompted the need to replace the existing roundabout with a safer alternative. The project has removed the roundabout, widened the four vehicle approaches to the intersection and provided a four way signalised intersection with full pedestrian provisions. The project has also included the construction of a second southbound lane on Mirrabei Drive from Paul Coe Crescent to Gundaroo Drive. This lane provides the additional capacity that is required during the morning peak for vehicles turning right onto Gundaroo Drive.
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.
