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

Stage 1 duplication of Gundaroo Drive is progressing, with a lot of construction work underway.

In February 2018 this project reached a milestone with traffic switching to the new carriageway between the Gungahlin Lakes Golf Club entrance and the Mirrabei Drive/Anthony Rolfe Avenue intersection. Following this traffic switch, work has begun to widen the existing roadway. Works are expected to be completed in the third quarter of 2018 with signalisation works to continue for a short time after this.

The expansion of the project as well as difficulties with the need to move significant utilities on Gundaroo Drive and Mirrabei Drive, and wet weather has meant delays to the project. We apologise for the disruption caused to residents and commuters due to this delay and want to assure the community that the work is being progressed.

Pedestrian Access Update

The below map shows the current pedestrian access routes through the site and an alternative route through the town centre that avoids most of the work site. Pedestrians are encouraged to utilise this detour if possible to avoid the construction area. Works are progressing to open the pedestrian path across the new bridge as soon as possible.

Traffic impacts

  • The current speed limit of 60 km/h will remain in place for the whole work site, with further reductions to 40 km/h as required.
  • Drivers are asked to be mindful of the changed traffic arrangements and adhere to the work zone speed limits.

The following map shows the traffic arrangements in place on Gundaroo Drive (current as at April 2018).
