Updates and announcements

Roads and Maritime services has moved to the next stage of major construction of the intersection upgrade on Lanyon Drive and Tompsitt Drive, Jerrabomberra.

Work involves replacing the existing roundabout with traffic lights to reduce congestion for motorists who travel through it during peak times. The upgrade will also provide better facilities for pedestrians and cyclists.

Guideline ACT has been appointed to build the new intersection.

This is a substantial road project and traffic changes are required to be in place during construction to ensure the safety of all road users.

The traffic management plan for this stage of the work was fully implemented on Monday 9 October. Roads and Maritime would like to apologies for the traffic delays experienced by road users and is currently reviewing the traffic management plan and the construction delivery plan for the project.

Roads and Maritime services would like to thank the community for raising their concerns, the traffic delays are not acceptable and work has started to alleviate some of the issues experienced. We are working closely with our contractors to monitor traffic conditions and we will be making adjustments from today to improve traffic flow. For more information regarding the upgrade please contact the project team on 1800 727 714 or email

Project background

The intersection of Tompsitt Drive and Lanyon Drive in Jerrabomberra is located on one of the major access routes into the Australian Capital Territory.

This intersection features a roundabout with dual lanes on each approach and a left slip lane on the west bound approach. The intersection is currently performing poorly with motorists experiencing traffic delays and queuing, particularly during peak times.

To determine the most effective design for the improvements Roads and Maritime Services has been carrying out investigations including collection of traffic counts, ground and utility surveys, geotechnical investigations and detailed traffic modelling with consideration of expected growth in and around the area.

Project benefits

  • Reduce the significant queuing being experienced by motorists during peak times
  • Reduce traffic delays for motorists travelling through the intersection during peak times
  • Improved road safety for all vehicles
  • Improved amenity for pedestrians and cyclists
  • Provides for future traffic growth.

Next steps

The next step for the project will be to award the tender for construction which is expected to happen in late June 2018.

Roads and Maritime will keep the community updated as the project progresses.
