Updates and announcements

Major work has started on the intersection upgrade which will improve traffic flow at the intersection of Lanyon Drive and Tompsitt Drive. Please see our resident letter (PDF, 164Kb) for the latest information relating to the project.

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.

Traffic changes will be in place during construction. Careful consideration has been given to managing traffic through the construction site to ensure peak flows are maintained.

For safety, motorists are advised to drive to the conditions, follow the directions of signs and controllers and allow five minutes of extra travel time.

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.
