Updates and announcements

Roads and Maritime Services has opened all new lanes and fully commissioned the traffic signals at the intersection of Lanyon and Tompsitt drives at Jerrabomberra.

The Australian and NSW governments jointly funded project of $12 million to improve motorists safety, traffic flow and efficiency at the intersection.

These upgrade improvements will cater for future increases in traffic volumes and pedestrian movements.

The opening of the lanes during peak periods will ensure delays are kept to a minimum and traffic flow is improved through the intersection.

Motorists should be aware that some lanes may be closed intermittently during off-peak periods for further works as required.

Work on the upgrade is expected to be completed by mid 2019, weather permitting.

We are working closely with our contractors to monitor traffic conditions and phasing times for the traffic lights will be adjusted as required

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.

The upgrade at this intersection 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.

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

Work on the upgrade is expected to be completed by the end of 2019 weather permitting.

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