Gundaroo Drive duplication stage 2

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 2 duplication works involve the construction of a second carriageway on Gundaroo Drive from Gungahlin Drive to the Barton Highway. 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 three roundabouts on this section of road.

June 2019 Update

Four lanes have opened to traffic between Nudurr Drive and the Barton Highway from Monday 3 June 2019.There will be off-peak lane closures as the project team finishes up minor works including landscaping.

The speed limit will remain at 60km/h until minor works are completed and conditions are deemed safe to reinstate the speed limit of 80km/h. Road users are advised to follow the directions of traffic controllers and road signage and take note of reduced speed limits.

Work is also now well underway in the section between Nudurr Drive and Gungahlin Drive. The project team are busy with utility relocations, removal of the redundant gas main and duplication of the two bridges in this section. Work will begin to construct the new lanes in this section in the coming months. The footpaths on the northern side of Gundaroo Drive (Gungahlin Lakes Club side) have been closed to facilitate this work. There are detours in place and pedestrians and cyclists are advised to please take care and follow signage.

The project remains on track to be completed mid 2020.
